[Max] I need help! / How to exclude the environment from the tone mapper?

« on: 2023-08-01, 04:23:51 »

Hi
I am using a photo in the environment slot. How to get the photo to look like it does when opened in photoshop/ any viewer? I do not want the environment to be affected by the tone mapper so that I can adjust my lights/ tone mapper and the 3D model matches the photo (colour/ saturation etc...?

Thank you.

Does it achieve something? Are caustics generated by reflections already enabled by default? Thanks.

[Max] I need help! / Struggling with brushed brass material

« on: 2022-04-02, 20:22:53 »

Hi

I am trying to achieve a brushed brass effect (see attached) on a large surface (a fireplace) and I am finding it very challenging.

I have tried the various Corona materials library presets, CoronaPhysical materials presets and Siger shaders presets without much success.

I think the difficulty comes with the fact that what looks good on a small rounded piece does not look good on a large, flat surface.

Could anyone kindly recommend some settings?

Thank you

[Max] I need help! / Interior lighting: Exterior light through curtains

« on: 2022-01-22, 02:58:38 »

Hi

Do you have any tips when rendering sheer curtains? I am not too worried about the curtains themselves (I used the Corona library preset) more about how they affect the scene. It used to be good practice with Mental Ray and Vray to render them separately and composite them in post.
Is light shining through sheer curtains affecting the scene negatively (noise etc...)?

I am happy to hear your tips on the subject.

Thank you.

[Max] General Discussion / 4K caxhe does seem to crush colours

« on: 2022-01-02, 05:09:43 »

Hi

4K crush seems to darken the image compare to UHD.

I was told that 4K was the recommended setting but it is not the default one (apparently. it can lead to some visual anomalies).

Any suggestions?

Thank you.

[Max] General Discussion / 4K cache? Granularity option. What does it do?

« on: 2021-08-26, 14:36:43 »

And how is it different from "Quality"?

Is there a way to tweak the cache for a "per scene" approach by visualising it?

Thank you.

[Max] I need help! / I need help with a specific metal finish

« on: 2021-08-25, 21:53:12 »

Hi There

I am struggling to create a material that mimicks the MacBook Pro metal, not so much the bump but the variation in tones. I realise that the macbook is curved but it is challenging to come up with this powdered metal look.

Any idea to put me oin the right direction?

Thank you.

[Max] I need help! / lighting through sheer curtains. Any tips?

« on: 2021-05-21, 12:28:20 »

Hi

What is in your view the most effective way to light an interior (light comimg from outside) with sheer curtains in the windows?

They affect the lighting quite a bit (I use the sheer curtain Corona material) and asd greatly to the render time.

I have experimented with selecting the curtain mesh and deselecting "cast shadows" in the object properties.
Or should I render the scene without curtains then the curtains on their own and do some Post?

Also, should the mesh be an actual mesh with volume or just a one-sided plane?

Many thanks

Do you know the reson for that?

The materials used come from the Corona library.

[Max] General Discussion / Curious about 4K cache as a secondary solver...

« on: 2021-01-26, 08:04:54 »

Hi

I understand that 4K cache is not ready to be rolled out due to some problems that it may can cause.

But what are they and when is it ok to use it?

Also, what are the main advantages of it? I read that it will eventually replace the UHD cache so that it must do some things well!!!

Thank you

[Max] I need help! / Question about environment map and Adaptive Environment Sampling

« on: 2021-01-18, 05:08:15 »

Hi

Does the adaptive Environment sampler work if there is no map in the slot it but only a white colour in the color swab?

And would it make any difference if I used a Coronacolor map in the slot instead of the white color?

Thank you
