Is there a way to import an exr file that has multiple render pass channels in-bedded in the file (like the render passes that is within blender) I can open the exr file and I can see the RGB image, the alpha channel, the depth channel, and the first channel but all subsequent channels show the top channel so right now the first one is the diffuse channel the next one should be the global illumination channel (which it states it is) but the image is the diffuse channel and so on down the line.
Sorry, I wasn’t clear enough. I’m not rendering out things in blender I was attempting to read an exr file from 3dsmax and vray. I am trying out different composite programs (autodesk composite, fusion natron) and wanted to see how blender worked alongside them. So far autodesk composite works the best (no surprise as they are the same company) fusion has issues with black fringing natron crashes a lot.
I’m attaching an image demonstrating what I said in the first post. If I plug in the combined port I get what is expected. If I plug in the diffuse filter that is correct to but if I plug in any other of the render passes I get the diffuse filter. What I see in the input node is not correct. Any way of fixing this?
Black fringing is from alpha premultiplication misinterpretation. Add an unpremultiply (or whatever it is called in fusion) operation before the problem part.
Just to follow up, I figured out how to correct the fringe problem. You choose a channel boolean for both the GI and lighting and set them both to Minimum. If you go on by the standard explanations online they tell you to use Multiply and then have long explanations on how to correct the premultipliction as there isn’t a tool in fusion to do this.
Success, I downloaded the new version of blender and now everything works great. Super easy to set up, and I didn’t have to add a SRGB like in Composite.
