[C4D] Bug Reporting / IR not refreshing on camera move with a keyframed values on camera PSR

« on: 2019-11-14, 16:07:08 »

When animating camera moves, the IR does not update the move if there's a keyframe on the camera. I've attached a recording.

STR: add keyframe to camera, move camera while IR is running.

[C4D] Bug Reporting / Mix material displacement rotation on previous material

« on: 2019-11-14, 15:41:19 »

I'm trying to make an earth, so I applied a beauty texture to a sphere, with displacement on UVW mapping. Earth material.
Then I needed to mask out half of the earth for the city lights on the dark side, so I made another material and added it to the earth in top of the Earth material with opacity masked with 3D gradient on texture mode. Lights material.



I needed to rotate the Lights material opacity to match the orientation of where the sun was shining from, but keep the lights map itself orientated the same way always, so I used a Projector on Spherical set to object in the self illumination tab of the Lights material to keep it in place.
So I'm only rotating the mask. Rotated it into position and my displacement map from Earth material moved with the lights mask. Earth material diffuse map stays the same orientation as it should.



STR: rotate top material on Spherical with underlying displacement material on UVW. Displacement should rotate, diffuse should stay the same.

[C4D] Bug Reporting / IR not synced with timeline when scrubbing

« on: 2019-08-13, 01:55:46 »

I've found some, what I think are transformation bugs:

New scene, just corona sky, create an object,  rotate it P -90°
Animate H rotation from 0°to 360°over 90 frames.
Start IR and scrub the timeline. What you see in the viewport and what happens in IR should not match This only happens if I rotate P to -90°

This first happened when I was importing a new object and it was not rotated right, so I corrected it to P -90° and keyframed the H rotation. Here's a short screengrab:

I've also uploaded a scene file.



I was able to reproduce this on Cinema R18, R19, R20 with Corona 4 and Corona 4(hotfix 1) on 2 different workstations using Window 10.

[C4D] Resolved Feature Requests / Volume material alpha channel

« on: 2017-08-02, 18:58:47 »

I'm working on an animation which involves some storm clouds being formed over a surface and here's my problem.

The volume material doesn't appear in the alpha channel of the final render, and I need it to for post process purposes. The whole thing is gonna be in a virtual studio, so I need to key it exactly. I can't even get alpha from the volumetrics render element - it's the same as the beauty alpha.
I have tried with overriding it with the corona compositing tag, doesn't help.
I have tried with material properties/advanced/alpha mode/ always white, doesn't work
I have tried the mask render element with appropriate material ID's and it didn't show up.

I need soft alpha on the edges, so the element can be quickly selected and cut from the background, so rerendering with default material doesn't help me much.

The refraction and translucency options weren't satisfactory, since they produce a surface on the cloud.

I also tried Keying in after effects, putting a solid color in the background via rayswitch directly visible, but I loose all the details on the edges of the cloud during the keying process.

Please, make it happen :)

Work in Progress/Tests / Foliage / exterior materials testing

« on: 2014-10-21, 18:22:54 »

Hey guys...

I've just started testing Corona about a week ago and must say, that I'm really surprised by its simplicity and how fast you can get things done. Coming from Vray, I wanted to test the translucency on various types of foliage, since I've always had a hard time achieving the right balance with it in Vray.
Anyway, here's my first render, testing the IvyGrower on some simple model with Corona and IBL. Any comments and critique (help) are very wellcome!

More images to come, once the project progresses a bit further, such as grass, trees, bushes and maybe some overall exterior shots.
