[C4D] I need help! / Re: Aberrations in reflections of phisical metal gold material

« on: 2023-11-30, 12:47:05 »

The OP it talking about the phenomena where gold reflecting gold seems to multiply the saturation/colour of the reflections so that they appear orange.

This is replicated in the real world (see attcheed) but certainly seems rather pronounced in Corona (It's looked odd to me before too).

I'm not sure if this is a shortcoming in Coronas material - or if the real-world metals always have more imperfections/coatings/grease etc which diminish the effect.

Hardware / Amount RAM Needed?

« on: 2023-11-27, 21:21:42 »

Forgive my ignorance. I'm thinking of building my first PC around a 7950X. But on my local shop's part picker - it keeps limiting me to 64GB of DDR5 RAM on the motherboard.

Is there something about DDR5 RAM that is limiting it to 2 slots? Is 64GB remotely enough these days?
I always thought that Corona was somewhat RAM hungry so my old 2950X pc had 128GB of DDR4...

have you double checked that the surface is definitely flat? No problem in principle (see attaced)

Wanna share the scene so others can check there's nothing odd with it?

Seems to work fine for me (see attached). Have you simply tried re-downloading the asset?

Ah, how interesting. Who knew!
(Although in my case the buffer area/extra padding was for Render Selected rather than Render region, where you could just make the region a bit bigger anyway.

Use render selected. just drag in the geo for that part.

On a slight tangent I do wish that it was possible to use render selected with some padding, as on areas with stronger DoF it wouls avoid dark fringing.

In your photoshop file go to Edit>convert to profile>sRGB. Is the banding still there?

The questions isnt about ''smooth shading' in that sense. The OP is talking about banding in his render.

What is the colour space that you are outputting to? And how are you getting it into PS? For "proper'' compositing it should ideally be 32bit linear AFAIK.

[C4D] Bug Reporting / Re: Corona 10 slower than Corona 9

« on: 2023-11-15, 14:53:29 »

Corona 10 has some strange results time-wise. Often it's extremely fast - and then minutes later, much slower.

I just rendered a glass of coffee (set to complete at a noise limit). It finished in 41 seconds.
I then made a small tweak to the mesh and added a couple of percent to a colour value. Then the scene finished in 4 minutes 15 seconds.

It's certainly got me scratching my head!

[C4D] I need help! / Re: artifacts on step files import

As mentioned above, Phong angle is the way to solve this. try different (lower) angles until the artifacts go away

Just bumping to let people know that this is my workflow too, and not a niche request ;)
Its especially useful for product visualisations etc.

I feel that the Corona Bitmap node needs an urgent update in general. There are several threads on this forum noting its various shortcomings.

[C4D] I need help! / Re: Volume glass and mat sticker

« on: 2023-10-31, 09:47:21 »

Try and copy real life is always a good suggestion. Is the label a separate object or is it a poly selection of the main glass?
If so you're mixing the refraction on the glass depth. It should be a separate label on top.

Use the split command to make a new poly object and apply your label to that instead
