A great look at using Corona for C4D with Architecture Selection of Substance Source:

Great article and very interesting for me as I’m also trying to use Substance Designer in conjunction with Corona for Cinema 4D. The only thing I can’t get to work is the IOR map. I can’t find the CoronaMix Texture in Corona for Cinema 4D. Is it missing in the Alpha or where can I find it?

Thanks.

Hi Toby,

You don't need to uses "CoronaMix Texture" node in C4D, because you already have the "Layer" option. You'll find by clicking on the arrow next to the map slot. It's very complete and has different type of blending too.

For the IOR map generated by Substance Designer, you need to set the highest IOR value you want on your material.
Example: I designed a Chrome with dirt on it in Substance Designer > In Corona, I put 20-50 in the IOR value (for chrome) of my standard Material, then I input the IOR map generated by Substance Designer in the texture slot, it will decrease the value of the IOR where the dirt appears. (Chrome ~ 20 -50 / Dirt ~ 1.4)

IOR map >  White = 100% IOR value  / Black = 0% IOR Value.


Hope this answer suits your questions.
Cheers

Hi Guillaume,

thanks for your reply. Awesome work in the article. I know the Layer option and tried using it but didn’t get the result I expected. And thanks to your answer I know why. I thought that using a Substance IOR map would overwrite the IOR setting in the Corona Material, but I still have to enter a IOR value to get it to work. Will it be correct if I just use the IOR map or will I have to blend it in a layer?

Best decision ever ;)
Imho the tutorials on allegorithmics youtube channel are the best choice for starting, also make sure you watch the unreal and especially the unity playlist. Doesn't look like it at first but a big part of those are about creating materials in substance designer.

I also strongly recommend Hugo beyers tutorials:
Free: https://hugobeyer.artstation.com/pages/tutorials
cheap one on steam: http://store.steampowered.com/app/441450/

Also, look for substance stuff from artists on artstation, they often have breakdowns of their materials, some even share a tutorial.

And most important of all:
https://share.allegorithmic.com/
Here you can download and analyze the graphs from other peoples materials :)

Last but not least, there is a discord chat with lots of people - including allegorithmic staff - which can help with all sorts of questions and problems
