OMG, I never knew. Makes life so much easier!
Thanks for the tip.

[C4D] General Discussion / how to deal with transparency in psd or png
« on: 2018-03-15, 15:43:59 »
Hi,
Is there a way that Corona can read the opacity directly from a file exported by photoshop (.psd, .png,...) in an alpha channel? Like a way to make C4D or Corona read only the alpha channel of the same file.
Currently when I want to cut something out, I make a different black/white file to plug into the opacity channel. However I find it this a cumbersome way of working, with a lot of assets to keep track of and was wondering whether there was a better way.
Thanks for any help.

Hi,
All great information.
Thank you.
The main problem was indeed the scale. I didn't scale things up upon importing, so that messed the whole thing up.
Once I had rescaled my project, I had a much better handle on the displacement.
FYI, the best results I got from putting the 32-bit map into a Corona-bitmap (so linear) - so that does work and I feel it works well.
About the IR: I'm perfectly fine with restarting it every time. It's just with my inexperience, I sometimes am unsure whether it is user-error or a development hick-up.
But I think it's great that we can use it already, so no complaints here. :)

Hey Eddoron, sorry for the late response.
Thanks for explaining that in detail, that makes so much more sense to me now.
Still learning about the whole PBR-thing.
I've been further playing around with the megascans-files, but this time the displacement is giving me trouble.
No matter what value I input, I can't seem to get it right.
At low values the result doesn't seem to budge (<1cm), higher values (>2cm) make the whole thing explode.
I've tried dividing the mesh further with an SDS-object, but that only seems to amount to rounder corners, which are not wanted, obviously.
Any thoughts on this?
Also, is it normal that the IAR needs to be stopped and restarted for every new value that I input in the displacement? Or would that be a bug?

I would love to see a tutorial come out on this too! If I've missed the result of this call, let me know where I can find it.
Even better if it included a workflow for C4D/Corona...

Just come to realize that probably this "normal vs vector 90 degrees" IS what makes it a fresnel-shader.
(Please correct me if I'm wrong, I'm a newbie trying to learn here.)
Still the same question though: do I load the glossiness map into the fresnel-slot?

@Eddoron: Thanx for helping out.
I downloaded all of the maps available, so I could play around with them and I did know I needed to use the glossiness-map (I've ignored the roughness-map all together.)
Somehow I failed to realize that the "mix-trick" he uses, was in fact the fresnel-shader. So thanks for clearing that up.
One question though: does this mean I have to load the map into the fresnel-slot in Corona also, or would I just simply play around with values? (within the dielectrics range, I suppose.)
And lastly, what is the "normal vs vector 90 degrees"-setting he selects?
@TomG: I know you guys are waiting for everything to be more final before you record more tutorials and I think we're all eagerly awaiting those.
@Ozwald: Having said that, I did learn a lot from watching all tutorials that exist for Max and tried to convert it all back to C4D. Works for greater part.

Hi,
Does anybody know of good tutorials where I can properly learn importing content from the Quixel Megascans library into C4D/Corona?
I found only this one, but it's for Octane.
http://cgterminal.com/2017/06/09/cinema-4d-stunning-environment-megascans-octane-tutorial/
I find myself out of my league when trying to convert this workflow to C4D/Corona.
If anybody wants to have a look, skip right to 7:22, all the import-action is between 7:22 and 11.58
I'm particularly interested in how to deal with the glossiness channel in C4D/Corona. He talks about it from 10:55 to 11:35.
Any help is much appreciated.
Thanx.
