Render Woes....

Stryder87

I've taken a previously working scene and edited it for a second scene in the same location, used the same characters etc.  However, as seen in the attached screenshot of the render, the skin has gone entirely white.  I seem to remember someone mentioning it a long time ago what could be causing this, but I'm drawing a complete blank here.  I've included a shot of the render dialogue box as well with an error that may be related.

 

Can anyone suggest how to fix this without having to reload the characters?  Having to recreate the poses alone would make me weep profusely....

It's like you've turned on emmissive & turned the luminence up way, way high.

It would be pretty impressive if I did since I don't know where those settings are and never changed anything when I changed the scene from the last one to this one. 

Oh, I guess I should mention this is in 3Delight.  haha

Oh, and two other characters aren't displaying this effect, and a third one is.

*facepalm*

Ok, this is just stupid.  In the process of the last 4 attempts at test rendering, I've closed Daz twice (this is over the span of 3 days).  All 4 test renders had the white skin on the three genesis 2 characters.  The Teen Josie, Teen Justin and the G3M were fine.

To do another check I just fired up Daz, loaded the scene and did some spot rendering.  On the first spot render, the dialogue box went through the 450+ Optimizing Textures messages.  It never did this on any of the 4 main test renders.  The 2 spot renders I tried went fine.  The Genesis 2 characters looked fine.  So I did a full test render.  It's working fine now too.

So, it would appear that it doing the Optimizing Textures thing fixed the problem.  The only issue now would seem to be... Why didn't it do it before this???  Is there a way to force it to optimize the textures for a render instead of having to do a render over and over until Daz decides to optimize?

It's a pretty common problem with the AoA SSS shader.  The trick is to force the 'optimization' process to run. 

You can do this by emptying your temp folder...which should happen when you close Studio...but it sometimes, like you found out does not.

A way to do this manually, without dumping the entire temp folder is to use your OS file manager, navigate to your Studio temp folder (if you look in the Preferences, you'll find where it is located) and then delete the contents of the brickyard folder.  This will force a rerun of tdlmake (the program that 'optimizes' the images).  This is because it has to rebuild the ShaderMixer network and all the old images are no longer valid.

Hmmmm... I can probably do something I've done before.  Create a batch file to empty the folders, then run Daz.  That way it happens everytime and I don't have to even think about it.

I figured closing Daz would have taken care of that, but yeah... apparently not.  Ah well... DOS Days to the rescue!  haha
