Reading on Stack (Facebook), I found this comment. Could this be implemented in Corona? (see attached)
Especially useful, I think, for Scatter objects.

I'm using a decal to project an embossed number.
When the mask source is from the material it works as expected, but when it comes from the "Map" slot it seems to form a contour.

[Scatter] Feature Requests / Improved Surface color texmap
« on: 2022-07-26, 16:15:31 »

Really enjoying Corona 8!

The Surface Color map is ok for very small objects, but it would be great if we could get the actual texture onto each instance, as opposed to just one single color.
Additionally, it would be good to have an opacity or blending mode, so we can mix the underlaying texture with the texture that each instance already has.
And finally a way to increase or decrease the size of the projected texture in real-world scale when applying a custom map.

Thank you.

It seems that the only way the corona distance map works with scatter is in legacy mode.

[Max] General Discussion / Very happy with V8
« on: 2022-06-27, 17:00:18 »
Hi all,

I just wanted to say that I'm very pleased with the new version 8.
So far I found many time saving features and improvements. From being able to use corona scatter instead of forest pack, to decals and the amazing slicer material. And it remains super stable!
Congratulations on what it is a great release.

EDIT: Also liking A LOT the new physical material from V7.

[Max] I need help! / Getting squares on IR refresh

Please, see attached.
I'm getting these squares on the grass when IR refreshes. I need to stop and restart it in order to get a clean image.

[Max] I need help! / Issue with PNG in Corona Bitmap
« on: 2022-06-21, 17:47:29 »
Hi all.
I'm not sure if I'm missing something, but it seems like PNG files are not loading well?
No problem with JPEG or TIFF.
See video please.
EDIT: 3Ds Max 2020, Corona 8 with hotfix 1

[Max] I need help! / Tone mapping presets and adding my own
« on: 2022-06-20, 00:19:44 »

Does the presets button and drop list menu take conf files from somewhere?
Or those presets are built in and there's no way to add my own?

Sorry if this was asked before. I couldn't find the answer with a search.



Is there a render element that shows two colors: one for pixels above RGB 1.0 and another for pixel from RGB 0 TO 0.99?

If not, it'd be very helpful to identify, with certain exposure and tone mapping, those areas that are burnt out.


Hi devs,

It would be great if one could add a modifier to proxy objects. In particular I find it would be very helpful to be able to add the FFD 2x2x2 in order to have more control when changing the dimensions.
Currently (version 7) I can add said modifier but it doesn't do anything to the proxy object.


Using "propagate masks" within a render element (CMasking_ID) instead of within the material would allow to have masks of one object with and without propagating them by adding additional CMasking elements.

Thank you.

If you could, please add a checkbox in the CoronaBitmap to use the aspect ratio of the incoming bitmaps.
This can be useful when using Triplanar mapping, since triplanar doesn't allow to use a UVW map modifier.

Thank you.

It would be helpful if the triplanar node could keep the aspect ratio of each bitmap.

This would be helpful when, for example, using coronaSelect with images that are not square.

Thank you


I'm using Corona Hair Material for a rug.
I need it to be very light, almost white, with a slight tint of light beige.

If I understand correctly, I'd need to lower the melamine to almost zero so I don't get the blonde hues. Also remove colored reflection.
If I do that the albedo is bright red. (why if I bring colored reflection to zero albedo changes?)

So I add tint to make it darker, but then the rug becomes too dark.

Is there an easy way to control the color while keeping the albedo non-red?

[Max] Feature Requests / Hair Material - saturation value
« on: 2022-01-07, 22:02:32 »
Hi there.

Please, add a saturation value in the corona hair Material.
I have a rug with two tones of almost gray hair. It took me a while to get both tones with the same saturation value.
