[C4D] General Discussion / Still some issues with hdri

« on: 2017-07-12, 22:19:05 »

Corona light with hdr image into emission slot
C4D sky with corona above light into his slot

In the viewport the sky is totally bright (burned) so i can't have a preview of the sky orientation.
Render is ok but the sky is always too bright, a little washed out and the scene lacks of contrast and vinrance.

Any idea/ suggestion?
Thanks

Ps: how it is better to set the hdri gamma value? Is there a rule?

(Beta 1 on mac os sierra).

[C4D] General Discussion / Illustrated Carpet

« on: 2017-01-28, 18:19:12 »

Hi,
I'm trying to make carpets with c4d hair simulation.
If I apply a material to the carpet, the material is applied in the same way to every single hair.
So if the material I choose has a bitmap illustration in the diffuse channel, the bitmap is applied to every single hair.
How is possible to apply in a way the whole carpet replies the illustrator bitmap?
I hope to have been clear...
thank you

Thank you Hog0. Switching off the glasses works well in this case..

I also tried to put a background sky mapped on a slice of a cylinder, and it works too.
The only problem is the the sun projects the shadow of the cylinder into the room. Maybe it is enough to set the cylinder to "non project shadows". I'll try this this evening.
Thank you again

PS: with the portal planes just outside the windows, the noise is less than an half.

Thanks
At which distance fron the glasses?
And for the glasses, is it better using real tickness (2 cm) or just planes with no tickness?

Thak you again.
How do u think is better to model the glass window? I used 2cm thick glass but i read it is better to use no thickness plan.
The other aspect i read is than is better to put the portal outside the window and not inside. I'll try to see the differences

Thankyou very much, i'll try everything.
2 questions:
Do i have to put the portal just inside the glass material? At which distance?
And for tue backplate with the sky image: jpg or hdri? Diffuse channel? And which distance from the window?
Thankyou very much
