Corona for Cinema 4D Beta 1 daily build

[Taiwolf]

Hello.
Can someone explain me why I get different results in using 2 types of lightning?
In the first picture I have used HDRI material( Light mat+Corona Output+HDRI) applyed to a environment override.
In the second picture I have used the same material applied to a sky object..Does somebody know why the results are different?

- Artifacts on poles are working fine (no artifacts) - FIXED

- AO map + mask texture (Max distance) still seems to be bugged. Doesn't mix as it should!

- IES files are working as before (as always here).

- As for the above post: difference in lighting - sky VS environment overwrite: works fine here - with same texture both results are same (in IPR & final)

-  Visibility via Compositing tag works fine, but Material > Advanced > Visibility options still doesn't.

Exploring on...

& JOYFUL HOLIDAYS TO ALL!!!

If you copy a textured object while the IR is running, you need to restart the IR to see it textured (until then, the default material is used for it).
Is this by design?

The IR with Sun creates problems only to me ??

Nope, I have problem with it also

Just installed latest build (today's) and IR will not start on complicated scenes (will start normally on empty scenes) and C4D freezes. Still investigating...

False alarm. Found the problem, one of the scene materials was causing c4d to freeze!!?? does that make sense? even when it wasn't assigned to any object... it was working with the previous version...

Hi Nikola,

it seems to work all right, except the Ir with sun.
I am attaching the scene
For the rest, you're doing a great job! :D

You are right, there was a problem with Sun in IR (in short, apart from Sun there was one additional light created in IR). It should be fixed in RC1.

Seems strange, do you know what material it was? Or could you send us that scene (or just empty scene with that problematic material copied)?

[tasmich]

Ales,
attached is an empty scene with the material that causes C4D to crash when starting IR. The scene I was working on is huge... The strange thing is that makes C4D crash even when its not assigned to any object!!

[tasmich]

Also, in the meanwhile I keep experimenting with some leather materials using IR and even though it works ok, it keeps freezing when changing material parameters... though I haven't identified anything specific.

Hi Tasmich,

You are using your scene with take system which I think making you problem. Try your scene without take system.

Corona runs smoothly.

[tasmich]

!!! Yes!! thats it...  thanks iacdxb. Strange though because over the last few days I have been using takes with corona without any issues!

Hello, Ales and Nikola.
I found another little trouble.
After the completion of the render, I noticed that the picture was overexposed. I adjusted some settings and saved the result. As a result, we got a picture with the reverse gamma correction.
I checked it happens because the Corona is a renderer. And this reverse gamma correction is visible when viewed in PDPlayer or FastStone Image Viewer.

It's not reproducible, so no bug report in the other section - but I happened to have some crashes with the IPR lately, also with the latest Beta (RC1).
It usually happens when I switch objects visible/invisible, when I add/remove objects or move texture tags from one object to another.
Anybody here with the same problems?
