Hello,
I am currently working on a project which uses cast iron type materials. To create these I have used a combination of cellular and noise procedural textures in the diffuse, reflection and bump slots. The renders look great and exactly what I need however they are taking far too long to render. Its 2 and half hours for a full HD frame of an animation. Normally we like to keep our render times to around 30 minutes per frame if we can. I am looking in to ways I can reduce the render times and thought that perhaps the procedural textures are the cause? Would it be any faster if I used texture maps of cellular and noise instead?
The render times do speed up to an hour and a half frame if I remove the maps from the reflection and bump slots and just have the diffuse and a solid reflection colour but it no longer looks and feels like cast iron. Also wondered if there are any other material tips and tricks I could try to get the render times down? I have stripped lights down to none HDRI plus turned off GI and it doesn’t make a dent in the render times so its definitely the materials.
Thanks,
