According to the tutorial, this is how the Shading Group should look like. 2 unanswered comment tells me that the problem is not solved. Now knowing that my Shading Group should be right the problem is still there. Moving on to I thought I could finally find a solution with this tutorial. There are some suggestions and i'm attempted to say "been there done that" So there is a tutorial this the same problem, and he newer solved the problem, as you also can tell in the comments. And I have lost more hair on a week and I normally do in a year. I have been using a week to search, read, try things out but nothing have worked to far.
#Renderman tutorial textures movie#
It is important to know that the light setup does not match as the lighting in the Maya seen have to match the movie I will put the car in. So this is how it look in substance painterĪnd here is how Renderman handle the textures. And I don't know why and what goes worng, and who to blame. Use PRMan-safe settings for tile size, planarconfig, and metadata.The translation from Substance painter to Renderman don't get the same result. Use OIIO-optimized settings for tile size, planarconfig, metadata, and constant-color optimizations. You'll probably want to use this flag if your image contains an alpha channel. Unpremultiply before color conversion, then premultiply after the color conversion. If the output color space is not the same bit depth as input color space, it is your responsibility to set the data format to the proper bit depth using the -d option.

Set the output data format to one of: uint8, sint8, uint16, sint16, half, float Specify the number of output image channels. Specify output file format (default: guess from extension) tx files and that involves maketx adding metadata that lets Arnold make more optimizations, such as being able to detect duplicate textures and only loading a single copy into memory or detecting constant color images, such as an all-black UDIM, and instead of storing all those black pixels in memory Arnold can special case that. The second level of benefit is only with. The previous level you could get from non-tx files that you saved with tiles and mipmapping. tx for the few images you are actively modifying if you don't want to wait for them to be constantly converted to. This should be considered mandatory, with the possible exception being don't use. These will dramatically improve time to the first pixel, overall render time, and allow using a smaller texture cache. The first benefit is that you are assured of having mipmaps and tiles. Maketx is a command-line utility to convert images to tiled, MIP-mapped textures, similar to txmake in Pixar Renderman. It is part of OpenImageIO ( ) and was developed by Larry Gritz at Sony Pictures Imageworks.
