Redshift 2 (free watermark version, requires Nvida GPU video cards) Renderman 21 (free PLE download, Pixar’s Renderer) I applied this all an successfully managed to achieve a close match to the original renders.Welcome to this page covering quickstart guides to three renderers… connecting the colour output to the shader input on the aibump node and the connecting the out colour value to the surface shader input on the surface shader node. This is done by inserting a aibump2d node between the shader and the alsurface node. Height map- As the bump map is already filled, another has to be added in the node editor. Insert the normal map, uptick the flip R and flip G channel, change use as to tangent spaced normals and then import the normal map set to Raw. Normal maps- no difference here than normal. Then in the node editor connect a texture node with the metal file loaded (with the colour value X) to the value x of the set range. In the output select the out value as X and the the input as specular1IOR.
I.O.R.- input a set range node into the colour map, doing this to remap the metal map onto some IOR values. This is because in substance they use the disney BRDF which is a GGX specular model. Why? In the node editor is is an out alpha and if it has no alpha channel, it is going to use the luminance of the RGB instead. Also, in the colour balance menu ensure alpha is luminance is checked. Roughness- import and change to RAW, as we only want to do gamma corrections on our colour images. Specular- this is imported and kept as sRGB. when exporting EXR- most software makes them linear, however substance painter does not, so they are still SRGB and you have to treat them as a jpeg or tif, so a colour space conversion is required.ĭiffuse- this is kept as RGB and simply imported I copied the type of file exported- in this case EXR.
Naming this the same naming conventions as the others with metal added on the end. He did this by selecting to create a new grey output. First he removed the FO output and created a metallic one. Doing further research, I found an easier technique by Nick Deboar.ĭeboar the Arnold export set up but altered it. Trying to convert the files using Arnolds standard AI materials requires a lengthy process to do so.
This is one of the biggest stumbling blocks for me- the conversion of substance painter textures to Maya.
