PBR Textures in Cinema4D

[Jim Scott]

I haven’t worked with PBR textures before, but have you tried loading those textures into the applicable channels of a basic material? For example: apply a basic material, open up its properties, select the Color channel, add your color texture through the Texture window. Repeat for the other PBR textures.

If you have a newer version of C4D with Reflectance, the specular texture would go in there. As far as gloss and AO are concerned, I’m not sure where to add those. Hopefully someone else can chime in.

Hope this helps.

I haven’t watched this yet, but perhaps it would be helpful:

I tried exactly that, but with the gloss and AO, it doesnt seem to work properly. It doesnt give me the results it should.

In realizing that I am completely ignorant as to the PBR process I would strongly suggest that you watch that video I referenced as well as do more research into the whole PBR process yourself. My initial suggestion came from that point of ignorance, but with a mind to help, and probably only confused the matter.

Good luck.

No worries! You are just trying to help! Unfortunately, as far as I can tell, the video doesnt seem to look at which channels one assigns which textures to, but I will keep researching.

I haven’t used PBR textures but my guess for R16 or R17 would be:

Diffuse: I’m not entirely sure about this one. I would have thought it would go in the color slot, but you also list a color texture so maybe diffuse goes in luminance?

Gloss: This goes in the texture slot beneath the roughness slider in a reflectance layer (click the arrow in front of “Roughness” to twirl down the option. Set the roughness slider to 100% to get the full effect of the map.

Normals: This goes in the material’s Normal channel. You may have to experiment with different settings to get the right result.

Specular: This goes in the reflectance layer’s Specular texture slot. I’d recommend deleting the default specular layer.

AO: this would go in the Diffusion channel.

If you can post a file with the textures I’d be happy to have a look.

Hi
I tried the channels you mentioned, but it doesnt quite work.
The files, as well as a gif showing how it should look are here: https://gamebanana.com/models/3434
I have spoken to the file creator, but unfortunately, he doesnt work with Cinema4D and couldnt help me!
I would really appreciate it, if you could tell me what to do.

Okay, I think I was able to get pretty close.

Here’s the formula I used:

Color: diffuse.tga
Diffusion: ao.png
Reflection: (see below)

I used the Filter in the Roughness slot to invert the glossiness map.

Thank you very much! It worked and it looks great!
