[Max] I need help! / interactive rendering restarts from time to time after a while....

« on: 2024-05-15, 11:51:11 »

Is there a way to prevent the interactive rendering from resetting and restarting? I am afraid that swapping windows tends to reinitialise it and I like browsing internet when rendering. Of course, the problem does not present itself when not using interactive rendering.

Thanks.

[Max] General Discussion / Is there anything to be gained from using the UHD animation prest for a still?

« on: 2024-05-14, 22:42:03 »

Hi

Would using the "animation (flicker free) preset lead to a better result than using the "still frame" preset quality-wise for a render?

Thank you

[Max] I need help! / Is there a way to use interactive render with batch render>

« on: 2024-05-14, 22:38:39 »

Hi

I often find that the fast denoising of the interactive renderer is good enough and for the same render time, a final (non-interactive) render looks much noiser than an interactive one (both use the same res/ render limit).

I have found that the "gather info" for denoising often leads to noisy renders.

Is there a way to do a batch render that would use the interactive rendering instead of the most thorough "final render" that denoises at the end? I also would like to automatically save my render elements

That would save a lot of time as I often have to do many renders in a short time.

I thought they were the same (as in they both lead to the same result)?

What am I missing here?

Thanks

[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.

[Max] General Discussion / Question about enabling "caustic solver" but not enabling "caustics" in materia

Hi

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.

Hi, with the final release of Corona 7, is the 4K cache now the preferred option?

Thanks

[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

I am using Corona version: 7 (DailyBuild Apr 21 2021)

Recently, my Corona materials show the following error message (see attached). I recently started using Corona 7 Betas.

Do you know the reson for that?

The materials used come from the Corona library.

Thank you

[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
