Hey guys, I recently purchased a model from TurboSquid. The model was originally created in 3ds max and the textures were done with V-Ray. I’m just wondering what the best approach would be in order to bring the model into Cinema 4D using Corona materials. The download did include an FBX and OBJ, along with image textures for the different channels, but plugging in the textures into the different channels of a Corona material and dropping it onto the object didn’t seem to work. Anyone have experience with this process?
Have you tried this converter?

I have not! I will give it a go 
Thanks!
No problem, good luck 
After giving it a try, I don’t think this will work 
I think that plugin is for taking V-Ray for C4D materials and converting them to Corona for C4D materials. I’m going to try a few other things, but thanks for letting me know about this plugin. It will definitely come in handy in other situations!
Long time now and which I remember… I think its for PC and now for Mac OS X also…?
…
So I’ve got the model open in 3ds max with Vray. Is there a way to get it into Cinema 4D with Vray? If I can get it to that point, I could use CoronaTools to convert everything to Corona materials. Gosh, this is ending up to be a bigger problem than I thought
max vray to c4D vary… yes, try this…
I hope it will help you and then you can convert to Corona.
…
this will work if you have c4d version up to 18.. if you are running c4d r19 then the plugin doesnt work and you will have to wait for them to release v4 (should be out soon i heard)
Hmmm interesting. I wonder if something like this would actually work descent. Anyone have experience with this?
Since these are Vray materials, I’m having trouble figuring out how to set up the materials. There are image files for:
- Diffuse
- Displace
- Gloss
- Lor
- Normal
- Reflect
I put Diffuse into the Diffuse channel, Reflect into the Reflection channel, Normal into the Bump channel (with Corona Normal shader), Displace into Displacement channel. But it’s not looking right. And I’m still left with Gloss and Lor images? Where do these go?
Gloss should be glossiness and Lor is rather IOR (I, not L) and would go into the IOR slot of the reflection channel.
I think
I often feel overrun with the various names of the texture maps out there and I am still not quite sure, for example, what to do with the AO textures some distributors offer (probably mixing with albedo/diffuse or abuse in some slot I have not yet thought of).
That’s how I use the AO, layer it with the diffuse and blend as needed.
I should add position, world space and thickness maps to my materials.
So I am not doing it totally wrong
Oh I gotcha. Dang it, they didn’t include an AO map 
I found this for adding the worn edges effect:
