[Max] I need help! / corona AO vs Vray Dirt

« on: 2023-05-25, 09:28:41 »

Hello, would it be possible, in the near future, to improve the "corona AO" a little like the "Vray Dirt" because the "Vray dirt" offers many more very useful options. For example in this tutorial, Jonas Noell proposes a method to make a foam material with AO Vray parameters that are difficult to reproduce with corona AO.

Corona Ao is much less flexible and configurable than Vray Dirt and this can complicate the task sometimes ... I'm sure some of you know how to recreate this type of material but my tests with corona AO were not at all conclusive .... On your side how would you achieve this type of effect with corona AO as effectively as with Vray Dirt?

Thank you in advance

[Max] I need help! / unliking far clipping camera and bugs with "no emit light" coronalightmaterial

« on: 2021-05-05, 16:09:01 »

Hello I have two difficulties with Corona:

1) _I am having problems when using camera clipping. Is there a way to turn off camera far clipping so that I can see the background (HDRI for example in environment). I don't know of a way to use camera clipping and a background environment at the same time (to avoid post-production) Have you experienced this constraint already and what would be the best solutions?


2) _In addition, in the case where we use a textured plane in "corona light material" with a background so as to have a background, there are very often rendering problems (the light does not pass well, there is materials problem) when you uncheck "emit light".
I read that it was necessary to deactivate "affect reflections" for it to work but this solution is not entirely satisfactory because it impoverishes the reflections ... In my eyes it is very important to be able to use these backgrounds without problems ( like vray and the true lightmaterial which works perfectly) because in architectural images we use these subterfuges very often!

Thank you in advance!

[Max] Feature Requests / Corona opacity map into Vray

« on: 2019-11-12, 12:28:06 »

Hi,

Is it possible to have the corona opacity map when rendering with Vray next ?
Until V4 it was not possible and it is very annoying when you always switch between these two render engines..
Thanksa lot

Regard
