[Max] Bug Reporting / Chaos Cosmos - Car brake lights material - Corona

« on: 2023-07-17, 16:33:43 »

Hi,

Is it normal that all the cars assets provided by "Fisherman3D" vendor doesn't have a red brake lights material when used with 3dsMax and Corona ?
The render isn't the same as the preview in Cosmos, everything else seems ok.

How is it possible without Vray installed to customize the material file where Cosmos picks his material ?

Thanks for your help.

[Max] I need help! / Corona material Converter - 3DSMax2021

« on: 2020-12-08, 11:35:42 »

Hi,

I've just updated to Max 2021 at the studio, but it seems that the Corona Converter doesn't do anything on the Conversion button click.

First of all, at the start of Max the material editor slots are full of Standard Physical Material. Before in Max 2018, I just had to click on conversion and all this slots were converted into CoronatMat standard slots, and that was great. now it doesn't do anything.

It's the same if I import some object with Forest who have a VrayMaterial. On the rendering it appeards as flat Red with an error message, and that's ok because it's Vray Material and I try to render with Corona, but before I just needed to click on version and all those materials were converted into corona mats and everything was ok. Does it need to have a version of Vray installed to correctly convert the VrayMat ?

Another quick help, does anyone now how to have already all material slots to be CoronaMat at the start of max ? That would be a great help.

Thanks a lot for your help.

[Max] Bug Reporting / Corona Sun + Sphere = Reflect bug ?

« on: 2018-02-15, 12:59:16 »

Hi there,

I'm currently having trouble with some basic reflections with Max 2018 + Corona 1.7 :

I use a sphere with a CoronaLightMtl and an environnement bitmap in the textmap for the reflect of my scene, and a simple CoronaSun to enlight all of this.
I placed a simple sphere with a glossy material to test show the problem : in the reflects the sun is dark and in a global scene it makes dark areas in glossy materials.



See attached jpgs to see details of mats and scene.

Has anyone a solution for this ?

Thanks a lot,

Herve

[Max] Bug Reporting / Forest invisible on Camera doesn't work.

« on: 2017-10-25, 16:25:45 »

Hi,

I would like to report something who doesn't seem to work for me, maybe it's the same for some of you :

I'm used to render scenes with Vray with Forest objects (trees) as non-visible for the camera (right click -> Object properties -> "Visible for the camera" UNCHECKED)
In sort of render just the shadows of my trees in my picture, but witouth the 3D trees... Let me know if you don't understand my case.

This is not working with Corona, and either not in the Interactive Mode, the Forest trees are still visible in the frame.

I just downloaded Corona 1.8 and it's the same.

Can someone check if it's also the same problem ?
Maybe someone have a solution to get around this and to have to results wanted ?

Thanks a lot for your help, and sorry if the subject was already treated.
