Substance Painter Materials In Cinema 4D Redshift IPR Slow

[michaelp78008416]

I am on a Mac with M1 Ultra and using the latest version of Cinema 4D and Redshift.  I am bringing in the .sbsar files directly into Cinema 4D to quickly make some variations.  My question is by doing this verses making variations in Substance Painter and exporting the multiple materials as Redshift materials does this increase renders time / IPR renderings?  Im guessing by using the materials inside of C4D and rendering there always need to be calculations done.  Just trying to boost performance and come up with optimal workflow.

Hi @michaelp78008416 , thanks for reaching out! In your particular case, the only intensive part will be in the initial loading of the .sbsar when the maps are being generated by C4D. After that, they are saved to disk and it should be functionally the same as if you were working with manually exported maps from Painter.

So what is the benefir of using the .sbsar then? The advantage of using an .sbsar with the plugin comes from working with materials that have exposed parameters from Substance Designer or Sampler. Those exposed parameters allow you to make adjustments to your material after exporting. Painter doesn't allow exposed parameters, so .sbsar files from Painter will still load your textures perfectly, there just wont be any post-export adjustments you can make.

The plugin is now officially maintained by the Maxon team, so please also consider reaching out to their support team for usage questions.

Cheers,
Aldo
