C4DtoA: Layer_Color now Layer_RGBA?

[Shawn_Kearney1]

I noticed that .ass files with Layer_Color will cause render errors, and even random a crash when rendered. I did a little poking around and discovered that Layer_Color is now Layer_RGBA. I also found that if I modify the offending .ass file by hand to point to the Layer_RGBA node instead it renders, and everything appears to look OK.

Would it be safe for me to go ahead and do this en masse for all of our assets? Will the shader network still wire up properly? Is Layer_RGBA backward compatible with Layer_Color?

ETA: At closer look, that will not work. The material renders, but the channel is black - as if disconnected. I noticed though that in the shader network the Layer_Color node does show up. But for some reason my .ass files that include it fail.

Yes, the layer and layer_color shaders are changed to layer_shader and layer_rgba, which have different parameter names and more blending modes in layer_rgba. The old shaders are removed and the plugin automatically converts them to the new ones when an old scene is opened. However, as you noticed, ASS files with the old shaders do not work now. I think the best idea is to bring back the old shaders, flagged a deprecated. I will make a bugfix release in the next days, including this.

Thanks for confirming this. I've fixed all the broken files. Fortunately there were not very many of them.
