[Max] I need help! / Re: geosphere as background

« on: 2024-04-24, 04:36:39 »

Interestingly, I just discovered that I had encountered this bug in my last scene without knowing where it came from. I had thought that my backplate was the culprit but didn't have time to address the issue. So thank you @leo_surrealismo for this very informative thread.

The workaround seems effective, it's always better than fixing the bug in Photoshop :) but I see that the post dates back to 2021: so it's not planned to find a fix in a future Corona version?

[Max] I need help! / Re: Corona displacement mod problem

« on: 2024-04-22, 02:32:32 »

As soon as I convert simple box to editable poly and apply unwrap and  displacement, one side of box got displacement and other side is "flat".

I'm not able to reproduce this issue. Every face of the box looks fine on my end, even when it's converted to editable poly and I played a bit with the UVs with the Unwrap UVW modifier.

Did you try to put the Displacement map in the material slot instead of using a modifier?

Thanks.
But this is not what he wants: he doesn't want to instance the rotation value, he wants a control to change the rotation of only one map, and the two maps being instanced.

Yes, I was thinking of that possibility too, but didn't find how to do that.
Could you explain a bit further?

You could try the following setup: plug the Default Output to the Environment slot, and apply a self illuminated CoronaMtl to a geosphere that will act as a "geometry direct override" if that makes sense.

If you rotate the HDRi, the rotation is reflected on the geosphere as well. But if you want the geosphere to have a different orientation than your HDRi all you have to do is to rotate it in the Top viewport.
You will have to find the correct orientation of the geosphere first so that its mapping matches the one of the environment slot, and play with the self-illumination intensity as well but this setup works.

I hope it helps.

Thanks for your comments Juraj. About the background, I've opened your render in PS, turned it into B&W and checked the exposure levels with the eyedropper: I was wrong actually, the exposure levels are correct, my bad. It's funny how it looked underexposed to me when looking at the original render, but it looks correct when turning the render into B&W. For some reason the colours tricked my eyes :-)
I totally get what you say about keeping the imperfections of the images, it makes sense when you work under pressure (it's hard to find imperfections in your images Juraj!)

Very impressive work as usual Juraj, thanks for sharing.

Here is a great rug tutorial by Pikcells:

If I may offer a critique, on the rendering with the woman walking with the coffee cup, I feel like the background is a bit underexposed (the curtain seems brighter than the outside). Apart from that ... perfect job :)

As always, I have great admiration for your glows on the windows. I'm eagerly waiting for Corona to one day produce glows as realistic as yours. Your glows remind me a lot of those by Bertrand Benoit or Jesus Selvera. I imagine you create them in post-production in 32 bits using software like ArionFX?

[Max] I need help! / Re: Invisible to camera but obscuring everything hidden by this object.

Maybe you could also achieve this by using a Camera Map modifier in conjunction with a CoronaRaySwitchMtl.
The first one to put the background instead of the object itself, and the latter to replace its reflection.

The beauty of the Camera Raw DOF feature is that you don't even need a ZDepth map :-)

I've never noticed the possibility of loading a ZDepth map in the native PS Lens Blur filter, thanks for that @Juraj.
Anyway I prefer using the new Lens Blur feature in Camera Raw, have you tried it? It's pretty awesome. Unfortunately you can't load a ZDepth map with it, but so far I found it sufficient for my needs, at least for exteriors with just a tiny bit of DOF. It may not work as well with interiors with strong DOF though, where you may prefer using the Corona Camera DOF.

I'm not sure why you enable bokeh if you don't want things to be blurred: bokehs appear in out of focus areas of the image. These areas are blurred, as Romullus said, this is how it works in real life.
That being said, if you want less blur you can play with the DOF so that out of focus areas are less prevalent.

Did you try to merge half of the objects and see if the problem remains? If no it means the culprit is the other half of objects.
Repeat the process in the other half and do so until you isolate the problematic object.
