Corona Material/Lights Converter (legacy)

[Noah45]

Having difficulties converting a Vray file.
Using the latest material converter, and Corona 1.3

In the screenshot, after executing 'start conversion', it does nothing.
There is an original Corona material (tshirt) and a corona light.

I'm wondering if the Client did something different w/ Vray, But a friend that has Vray, has no problem with this file?

Hi. You need to have Vray installed to convert Vray materials. Don't know if that's the problem, but it sounds like this.

I think there is a trial/demo version of Vray that will make conversion possible.

[Noah45]

I'll try it, but did not need VRay on earlier conversions

Workaround for tonight... my Vray licensed buddy is exporting as .3ds. (deadline a.m!)

The converter needs vray installed if you want to convert vray classes. Without having the plugin running, max has no idea about these materials, their properties and so on. But it has always been like this (and will be in the future) ;)
Installing the Demo version of vray is sufficient.

Hi Martin, not sure if i'm doing it wrong or selection modes are broken in converter v1.20. I have a bunch of bitmap nodes in slate editor and i want to convert some of them into CoronaBitmaps. I select those specific nodes in SME, choose "selected material editor slot" in converter and press start conversion, but it converts every single bitmap node in that view, not just selected ones.

[racoonart]

mhhh.. I'm not sure if I remember it correctly but I think maps do not respect the selection modes. So you either convert ALL materials + maps or just the materials themselves (excluding maps) via object or material editor slot. It's due to the way I'm collecting the map instances and also to avoid breaking instancing between materials =/

[romullus]

Looks like there is no option to do that at all? :/ Maybe it's possible to force converter to respect SME views, so we'd have at least some workaround - move necessary nodes to separate view and convert all maps only in that specific view?

[racoonart]

Doing stuff for slate is quite... unpleasing.. to put it this way ;) . Or at least has been in the past, haven't checked lately. Would it be sufficient if the current selected mtl editor slot converts whatever is in there? Either the map or the material + the maps used by this material (possibly breaking the instancing).

[romullus]

Well, not very usefull for me, but still better than nothing. No rush, though.

Oh, and i couldn't care less about keeping instancing, since in slate it's quite easy to tell whether node is instanced or not :]

Regarding the Noah45 problem: you can see that the red material says "missing material" - so it is not something which did not get converted, but simply a missing material.

[Noah45]

Thanks for responses.  OK. I need to find out what the client did differently to these files.
