    Canvasses are actually quite an amazing tool that comes with Iray.   Using them with Light Groups is incredibly powerful, letting you adjust lighting completely in postwork.

    Then you can move into actual light path expressions (LPEs) that let you not only specifiy the light source, but the actual lighting path to render.  That lets you render the impact of specific lights on individual objects.

     Wow... Thanks TB. Looks very powerful indeed.

    I've just added the 3rd Animation Club for Carrara's anim link to WGD Crazy Artwerks.  This was a group effort in which I only contributed a rough Intro anim which thankfully mmoir improved upon along with about 5 objects created for this project.

    For 3Delight there is a free script to render each single light source in a scene to a seperate image: http://www.daz3d.com/forums/discussion/38514/#676252

    Now you can combine the layers in postwork, similar to the Iray canvasses.

    Oh, that's cool.  I'm just now figuring out RIB and render passes and stuff in 3DL.  So far, the Iray canvases were easier to figure out thanks to the two tutorials I linked earlier.  I'll have to check out that thread and see if it answers some of my questions about it.

    Number 6, I'm not sure about that.  It isn't something I've needed to do yet, but I'll look into that and get back to you.  If I can understand what you are asking and can find the answer and understand what I'm doing, I'll do a tutorial to explain it.

    I thought that PSP had this but I couldn't find it tonight... could have been a diff program. What it does is when the, let's say... left side of image moves off the screen at left it moves onto the screen at right side... as if it is one continuous image.  By adjusting it to move x and y to the center of the scene a self tiling image can be created.

    ---------------------------------------------------

    PSP has this. It is an Effect. It's under Image Effects\Offset. You have to use the wrap option.

    Photoshop also has this as a Filter. You can use it to create a seemless texture.

    I image GIMP has this too. I'll take a look and see if I can find it.

  • Kev914Kev914 Posts: 1,115

    In GIMP, it is under Layers, Transform\Offset. You can enter pixels, inches etc that you want to offset. If you want to offset exactly in the middle in both directions, there is a button in the middle of the panel for that so you don't have to calculate diminsions.

    Anyhow....I think this is what you meant.

    Thanks KevinH,  Thought it was in PSP... was looking too frantically the other night. :)

    KM,  I installed GIMP 2.8 last night and have a few questions... don't bother to answer those you will cover them in a future tutorial.

    1. How can I get GIMP 2.9?  I checked the Gimp website but was unable to find a download version. I'm running Windoze 7. No big problem as I can wait for 2.10. :)
    2. Regarding a learn mode for scripts... I could not find this referenced anywhere in the online documentation/help files. Having just installed Gimp I didn't think to look for example scripts which would likely be enough for me... I like writing scripts and programming... which makes my brain work harder.  Question I have is what Gimp calls Python FU a true Python script or Gimp's flavor of Python?

    TIA, John

  • I'm running a little behind as I wasn't on the computer much today.  I was busy with non-computer related projects.  I should have the new tutorial squared away and posted sometime tonight after I get back home.  I'll look into the Python thing, but I think it is regular Python script, but not positive about that.

    In the meantime, check out the Partha compilation of Gimp 2.9.  It is all set for using the NIK filters.  You still have to download those and install them, but once they are installed, Gimp 2.9 knows where to look for them if they are installed in the default place.  Not sure what happens if you install them somewhere else.  You might have to change where Gimp 2.9 looks for them.  I'll have to double check which script it is that looks for that in the Partha distro.  You want the experimental version that is the first download option under Windows about halfway down the page.

    I'm on my way out the door.  I'll be back later.

    I am looking forward to the new lesson (Tutorial)!!! 

    Have a great evening KM.

    Gimp 2.8 Rectangle Select Tool - Part 1

    Black text didn't show up well in this image so I chose red.  I'm not sure the red works either.  Let me know if it is readable.  I may go back and change it.

    I'm sorry this was later than I expected to get it posted.  Today just got away from me with things around the house and I had a render that just would not finish.  I have another Part to this tutorial of things to do with the Rectangle Select before moving on to the next tool.  I'll try to get it posted soon.

    Homework:  Open an image in Gimp and work with the Rectangle Select.  Crop and image.  If you post an image to the thread, please upload a before and after cropping so I can see how you did.

    edit: forgot the Modes Image.  Added that.

  • After I cropped Willow for the tutorial, I couldn't resist doing a little Gimp magic on her with a few filters on a couple of different layers.  I think she's rather cute.  :)

    Thanks for all the info about GIMP. This is really helpful.

  • Kev914Kev914 Posts: 1,115

    Just wondered how you created the backdrop in your Willow image, @knittingmommy?

  • @KevinH  I actually forgot to put that info on my picture in the gallery so thanks for asking @KevinH.  That is just the Multiplane Cyclorama.  It's an old product, but I still find it very handy for situations like this.  The image is from the Cyclorama: Portrait Paper Backdrops.  The wooden fence and plane I used on the floor, that added some reflections to it, came with Willow.

    No problem.  I'm having fun and hopefully everyone will learn something new.  I've been working on the next tutorial this morning and I'm almost finished with Part 2 of the Rectangle Select Tool and it should be posted soon.

    Gimp 2.8 Rectangle Select Tool Part 2

    Homework:  As the last screenshot says.  Go Play!  Let me know if I left anything out or if you need further explanations or run into any problems.

    Part 3 of Rectangle Select Tool in a few days.  Yes, there is more!

    edit:  I just realized that for the second image, I uploaded the wrong image.  I've fixed that and the correct image is up there.  Sorry about the mistake.  If anyone looked closely, images one and two had contradictory information.  The third image had the correct information.  I originally had that infor incorrect on image two and then deleted it and added the correct info on image 3, but accidentally uploaded the wrong image two.

    OK!! That was sure a lot to take in so I am going to have to go back and read it a couple more time to have it sink in.....I will have this done by tonight both homeworks.

  • Well, you have a couple of days before the next tutorial so you have time.  :)

  • Looking through my tutorial, I didn't specifically spell it out, but the instructions for using the modifier keys, Shift, Ctrl and Shift + Ctrl are the other three modes if you didn't already figure that out.  You could also click on each of the other modes with the mouse.  I just find the modifier keys easier to use in this instance.  If anyone got confused by that, let me know, and I'll figure out how to reword the tutorial and update to include that information.

    So, DS is rendering and I was bored this evening and thought I'd go into Gimp and play.  I took my Willow image from my Gimp Tutorial and messed around a little bit.  There are still tons of filters I haven't played with yet.  I found a few cool ones and I did some interesting combing combining of layers to get some interesting looks.  There area  couple I will definitely play with some more and learn everything there is to learn about them.  Anyway, I'm sharing.  :)

    You would not believe the trouble I've had with my latest render!  When I saw the Christmas Dinner set by @Bluebird3D, I thought it would be perfect for a Christmas Card.  Yes, I know, I'm running late getting those kinds of things out, which is why I usually end up not doing them.  I thought I'd be different this year and actually send out some cards.  I started this in Windows after I finished the last Gimp tutorial since I was in there anyway.  Big mistake.  First I couldn't get it to render like the promos.  None of my settings came away looking anywhere near as pretty.  Turns out, Smart Content was hiding a few things which is why I usually never use it.  I don't know why I was this time.  Probably because I miss having any kind of CMS in Linux since I still haven't gotten that working yet.  

    I've gotten lots of sets from Bluebird3D and she usually always includes cameras and lighting.  I don't know why Smart Content was hiding those features.  I finally ended up going through the product tree under Content Library instead and found the cameras and the lights and even found that Charlene had included a Render Settings preset.  Fun!  So, I used that and started rendering again.  It looked much better.  Unfortunately, I seemed to have managed to get a virus or malware on Windows and ended up crashing everything after 2 days of rendering when I was trying to fix that.  Hint, don't try to to fix virus issues while rendering!  I ended up reinstalling from a clean backup since my render was trashed anyway.  Man, I really hate Windows at times.  One of these days, I hope to be completely free of it.

    Anyway, since my render was totally trashed, nothing even the temp folder to rescue, I went back to the safety of Linux and started over.  So, almost 4 days later, I managed to get this:

    A very nice render and it almost matches one of the promo shot that I thought would look so great on a Christmas card.  I widened the camera a bit and moved the chair a little.  I'm not sure why mine is a little darker.  The promo looks a little brighter.  I might try playing with curves on my original to see if I can get it to look like the promo sometime, but for now, I like what I managed to get with my own postwork attempts.  I took it into Gimp and did a little postwork to match more my style of what I wanted it to look like.  

    I think it turned out really well.  The differences are subtle, but I like it.  Now, I just need to get the cards printed and actually send them out.  :)

    So, I did a quick tour into the Brightness/Contrast filter in Gimp.  It might actually be better.

    Thanks, Sonja.  Turns out I like playing with Levels and Curves much better than the Brightness and Contrast.  I think there is a little bit more control over how it works.  Anyway, after playing with Curves, I think I have a final version of this.  It think the table cloth isn't quite as blown out as in the version with the Brightness and Contrast version.

  • That came out really well, @Knittingmommy!

    Now all you need are some kids running around to knock the water pitchers over and pull the tablecloth to the ground........

    Thanks. @TabascoJack!  That about sums up Christmases past at my house.  :)  I couldn't resist taking off the white tablecloth and seeing how the table rendered.  It's a beautifully done table under that white tablecloth.  I'll have a render of the table finished soon without all of the table settings.

  • IceDragonArtIceDragonArt Posts: 12,548

    I agree the final one the tablecloth is a touch less bright, especially around the edges

  • The dining room looks excellent!  But I got to ask about the light emanating from under the table? 

  • KnittingmommyKnittingmommy Posts: 8,191

    Thanks, @FirstBastion.  :)  

    I have to admit that surprised me a little bit.  That light emanating from under the table is a sphere turned emissive.   Charlene (Bluebird3D) set that up and it comes as part of the full lights preset.  Very cool.  I'm not sure I would have ever thought to put a light under the table, but it really does help with the lighting.  Here's a screenshot with part of the surface settings visible.

    Here is the test render of the table without the tablecloth.  I love the wood grain on it.  I stopped the render early so there is still a bit of grain, but I didn't want to do a another 3 day render for a test.

    Again, I took it into Gimp and played with the Curves just a little to brighten it up.  I love how the wood grain seems to pop out.  Excellent textures there.

    That sphere is more visible without the tablecloth.  One would probably have to come up with a different way to add more lighting if not using the tablecloth in this room.  I think I'd probably make it smaller and maybe raise it off the floor a little bit if I were to use it for an actual render without the tablecloth.

    KM,  that's a very good set for Christmas Dinner... nice render also.  Last night I modeled a dinner plate, salad plate and pasta bowl and 2 diff sizes of straight sided glasses for the ACC.  Tonight I purchased a full set with flatware from Rendo... probably have more than a few sets from DAZ.  Last time, quite a few years ago, that I tried modeling flatware it was disasterous... know I could do better now but haven't tried.

  • Thanks, @wgdjohn.  I haven't tried modeling all of that stuff yet.  I'm still very new to modeling.  I've only done one glass and a coffee mug, so far, when it comes to tableware.  I need to finish up my current Blender tutorial so I can get in in DS and rendered.  I'll post my latest Blender models soon.
