Just trying out @RyanB 's impostor plugin: http://www.shaderbits.com/blog/octahedral-impostors
I’m a little lost when it comes to the material setup. I can see in the description that if I want to include other maps like Subsurface, I need to add that to the material myself. Seen as the output is a material instance it’s a little confusing: do I modify the parent or do I modify the material function that is the base of the parent?
My results aren’t quite as good as the example given on Ryan’s blog and I’m assuming that’s due to lack of Subsurface scattering. The impostor on the left of the first image is the exported static mesh with the generated material instance applied to it.
In the attached images, you can see that the colour isn’t quite right and looking at the impostor with the sun behind it washes it out and causes weird highlights on the trunk.
I’m assuming there’s a step I’m missing or a setting I’ve not configured properly?
Any help would be appreciated.
