[Max] Feature Requests / IR clipping for isolated preview with correct lighting

« on: 2019-01-18, 23:40:00 »

In archviz scenes can get heavy to the point that IR becomes too slow unless you isolate objects.
The problem with that is that you're viewing the objects with the wrong lighting.

For example, if you're working on an exterior scene surrounded by mountains, and you isolate the object, the sun that was hidden behind the mountains now hits your objects. This forces you to change the exposure all the time (unless you also select the mountains with your objects, not practical though).

It would be nice to have a corona isolation mode which would be a "sphere" that acts as a region of interest for the calculations.
Actually two spheres, one inside the other. Anything in between the spheres would not be considered in the calculations, and only anything inside the smaller sphere would be shown as rendered pixels.

The input would be 2 dimensions for the radiuses.

Thanks.

[Max] General Discussion / Want to have speed improvement for free? Suggested settings for speed

« on: 2019-01-17, 17:30:32 »

Hi,

If you want to render faster, change these settings from the defaults.

In the Performance tab:
Max Sample Intensity to 1

In UHD Cache, also in performance:
Precision: 0.1

You'll be able to compare the difference better if you set IR Subsampling at 0, in Performance/Development/Interactive rendering.

Does anyone suggest anything else to speed rendering up?

Thanks.
Guido.

[Max] I need help! / How do I reduce the strength of secondary bounces (color bleed) globally?

Hi there,

I feel that the color bleeding is too strong in general. How can I reduce it globally and not with rayswitch?

Thanks.

[Max] Feature Requests / Atmosphere based on Z-Depth as post effect in VFB

Would it be possible to have a cheap (to compute) atmosphere based on the z depth channel, available in the tonmaping area?

[Max] Resolved Feature Requests / Physical camera to corona camera

« on: 2019-01-06, 18:55:56 »

Hello.

Is the way to convert a physical camera to corona camera to add a CoronaCameraMod? Or is there a script?

Also I have over 80 cameras in a scene. Is there a script to add the CoronaCameraMod to all of them automatically?


Thanks

Hi there,

Is there a built in proxy lister or the following is the best for now?

[Max] I need help! / Is this possible with corona? (proper brushed metal)

« on: 2018-11-26, 00:29:33 »

Is the effect shown in the video below possible with Corona?
No matter what I've done in the last couple of years, or since I saw this video, I was never able to replicate this effect with corona.

I don't know if it's that bump map behaves differently than Fstorm or if it's an AA issue.

Is it possible to do it at all? Or I'm wasting time trying?

Thanks!

[Max] I need help! / Only one processor working every change while interactive rendering

« on: 2018-08-23, 17:19:03 »

Hi all.

The image shows my processors working while interactive rendering. When I make a change in the scene, only one processor works for a while.
Is this normal?

Thanks.

I'm using Max 2016 and Corona 1.6

[Scatter] I need help! / Corona scatter 1D on splines - Using scale map?

« on: 2018-04-16, 17:59:46 »

Hello,

I used before a scale map for corona scatter as described on this tutorial:

It doesn't seem to have an effect on corona scatter set to 1D with splines. Is this correct?


Thanks.

[Max] I need help! / Corona distance problem with certain shapes.

« on: 2018-04-08, 23:05:02 »

Hi all,

Any idea why the attached is happening?

My goal is to use text to make a boolean with CoronaDistance in opacity. But I keep getting these artifacts with text mostly (even after converting to editable poly).

I'm using Max 2016 with Corona 1.6 hotfix 3.

Thank you.
