    The more I play with it, the more I like it.

    Anyway, I have a few more questions :

    Is it possible to create an EXR output using Luxcore ?

    If not, is it possible to export a LXS file to render using Luxrender ? (I have Luxus , but I would have to change all the materials).

    Is emission plugged in ? I did some tests and I can't really see the result. Maybe I'm using wrong settings (I've checked the normal, so it's not the issue).

    Don't have the dragon 3, but I tried the Ready to Render scene "dragon slayer" and it worked.
    Quality is bad because the light rig is made for Daz studio, but till getting a render without any modification to the original scene means that Luxuscore is good at translating the materials.

    With the last build no, but with this new build YES.

    - http://sphericlabs.com/preview/win64/LuxusCore.zip

    You will need to put something like the following in the config section:

    batch.periodicsave=15
    film.outputs.1.type=RGB
    film.outputs.1.filename=image.exr

    This means every 15 seconds write an RGB image with filename image.exr. The file will apear in the extension folder.  You can specify a path such as C:/Users/Spheric/Documents/image.exr

     

    You could also do stuff like write an HDR and a tonemapped png with

    batch.periodicsave=15
    film.outputs.1.type=RGB
    film.outputs.1.filename=image.hdr
    film.outputs.2.type=RGB_TONEMAPPED
    film.outputs.2.filename=image.png

     

    types can be: RGB, RGBA, RGB_TONEMAPPED, RGBA_TONEMAPPED, ALPHA, DEPTH, POSITION, GEOMETRY_NORMAL, SHADING_NORMAL, MATERIAL_ID, DIRECT_DIFFUSE, DIRECT_GLOSSY, EMISSION, INDIRECT_DIFFUSE, INDIRECT_GLOSSY, INDIRECT_SPECULAR, MATERIAL_ID_MASK, DIRECT_SHADOW_MASK, INDIRECT_SHADOW_MASK, RADIANCE_GROUP, UV, RAYCOUNT, BY_MATERIAL_ID, and IRRADIANCE

    Thanks for the new version.

    Any update on when a GUI will be added or what other features are planned next?

    Thanks again!

  • Philemo_CarraraPhilemo_Carrara Posts: 1,175

    That's great news.

    So, to make it short,  now:

    • I can create HDR background (or Luxcore infinite light) using the spherical camera
    • I can use an external program (like picturenaut) to tonemap my render.
    • I have multipass capabilities with Luxcore
    • I can have periodic saving of the render (two days ago, Windows decided on its own to reboot my computer near the end of a long render to install a new update).

    You're really making something of it. I don't want to re-ignite some threads, but I think that's people like you who'll make Carrara stay alive a little longer.

    Thank you for that.

    These are game changers and something I have long wanted to be possible! Thank you for all the great work you are doing!

    Great stuff. FYI, tried to add alpha channel as described for luxus:

    luxcore toplevel shader ->
      luxcore mix​ ->
          material 1 -> luxcore matte
              color -> luxcore color​
          material 2 -> luxcore null
          amount-> texture map

    ​​Upon selecting texture map, carrara crashes.​ 

  • LotharenLotharen Posts: 282

    This is exciting to see. Will it support the rendering of tree leaves and particle effects/Carrara hair?  If it dose that - take my money now, lol. Is there a list of features it will have?

    Is there an eta from release on this plugin?

  • evilproducerevilproducer Posts: 9,050
    It won't do Carrara's hair.

    But it does do volumetric lighting prop[erly :)

    Maybe I am using the wrong fileformat for the image map. Are TIFFs ok?

    I'm testing this, and it looks nice and all...

    Problem I'm having with it: I cannot render image maps, it freezes up Carrara every single time, if I put just a regular color thing in diffuse channel it works, anybody have problem like that ? smiley

  • YofielYofiel Posts: 204

    Yes, that is what I am finding. i tried putting all the image maps in external compressed tiffs (pcbyte ordering) which is the Collada default format, and I still have the same problem with image maps.

    So, does anybody have any idea what Lux shaders are actually working in this latest version, I cannot render glass objects properly in GPU mode (maybe i'm doing something wrong, lol) ? smiley

     

    For some reason test scene (with cube and sphere) renders completely black crying When I switch to CPU it works, wierd sad

    all i can get is multiple 1's on the screen this is the same thing i get before it goes to lux render in luxus original but it never goes any further in core

    well that or solid black screen that never does anything

    Ok i loaded a preset and changed nothing but the renderer to core and it works fine but if i change a shader or light it renders black again i have run luxmark and my system should be bad ass at rendering with luxcore but all i seem to be getting is frustration. I was rendering in luxus/luxrender proper earlier and a single frame takes way too long I need this to work in earlier versions i had it working and did an animation that was amazing now i can't do a static image.

    i see now its the image map thing other people have mentioned but it wont render emisive shaders either

    I wish this had the support that Reality has.

    Not sure what the problem is.  Do simple scenes work?

     

    Sometimes its is helpful to see things setup. Here are 4 images that show:

    1) png image map

    2) tiff image map

    3) Glass

    4) Emission

    Hi Spheric.

    Yep, that is how glass surface was set in your test scene (i changed nothing in it), I just hit render and that's it, in CPU mode works fine, but in GPU entire scene renders black, other surfaces I tested work fine in GPU mode (architectual glass, for example) as long as, of course, ALL textures are saved externally.

    I also have problem with bump/normal mapping, how we actually define intensity of bump mapping in Lux ?

    Another thing, does Gamma slider works for LuxCore Infinite light ?

    Here is a GPU render of a very simple test scene of mine with LuxCore CarPaint material, when I switch it to LuxCore Glass material (which is set up exactly like in your example above), it fails again, renders all black, it works in CPU mode though sad

    Try adjusting the roughness(U and V) to 0.01.  Make it so they are not zero.

    Thank you for reporting your check on image formats. Are you using a PC or MAC byte ordering for the TIFFs, and are you using image compression for them?

     

    The images you shared are not openable at higher resolution for some reason.

    For those having trouble rendering using thier GPU (black screen at 0.0 s/s), try the following config in the render room "Config Settings" box:

    renderengine.type = "PATHOCL"
    opencl.platform.index = "-1"
    opencl.cpu.use = 0
    opencl.gpu.use = 1
    opencl.gpu.workgroup.size = "64"
    accelerator.instances.enable = "0"
    opencl.kernel.options = "-cl-fast-relaxed-math -cl-mad-enable -cl-no-signed-zeros"

    To render with both CPU and CPU change the opencl.cpu.use value to 1.

    Well, that worked, thanks, have no idea why, only problem is the last line of code : opencl.kernel.options = "-cl-fast-relaxed-math -cl-mad-enable -cl-no-signed-zeros".

    It crashes Carrara, have no idea why as well sad

    I pulled that all from the LuxMark config (which was rendering on my GPU perfectly) so that last line may not even be necessary. If it renders without I'd just leave it off.

    Thanks stringtheory9, Here is the image I was working on smiley

    Rendered in with LuxCore and composited in Fusion.

    Pain in the behind without shadow catcher in Lux, but nevertheless ...

    Where did you find that awesome DeLorean, and does it have a Flux Capacitor and Mr. Fusion morph? ;-)
