Colimo Alternative

[Adam Glover]

Hi

 

I've been using Motiva Colimo to take a render and then quickly roll out lots of versions of the same scene with different diffuse textures while keeping lighting and reflections etc unchanged, all in post without re-rendering each time.

 

This software is temperamental to say the least and crashes constantly.

 

Does anyone know a way to do this with other software please?

 

Or have any experience with Colimo 1.8 to advise me how to avoid these crashes?

 

Thanks

 

Adam

I never heard of Motiva Colimo before your post, but in discussing it with a colleague, this came up:

 

https://github.com/Psyop/Cryptomatte

 

It seems similarly inclined, but perhaps a bit more stable.

Thanks very much for posting a reply Corey.

 

I have never used nuke before so its a bit confusing.

From a quick look at the page you linked to it seems like it produces some sort of matte/mask.

Will this allow me to replace a texture with another in just a couple of clicks and have the texture line up exactly.

For example if I had a coke bottle render could I change the label from 'coke' to 'diet coke' by simply selection a new base texture and it line up perfectly?

 

You can composite all the vray passes in nuke or AE etc but this colimo is able to keep the UVW information at the same time which is something I am having a hard time finding other programs/methods capable of doing.

 

(The reason we chose to use Colimo originally was because its so simple that we can get an intern to do it with little or no training.)

 

Thanks again

Well just like Colimo not really, similar? well there are a few options, but you need to sacrifice something.

 

This is the Foundry take on a similar software.

You could go this renderer too.

Or the similar software but Autodesk version.

But this are more oriented to product Viz than Architectural Viz. But if the scene is not too large it may work.

 

Using NUKE or Fusion, it may be a good solution but instead of using only 2D exr, you can eventually use 3D geometry. maybe a mix of 2D and 3D . If you do this, then you keep the UV Mapping for the 3D objects, so just switching the texture, will be pretty easy.

While I completely understand your need for this type of feature, I have no idea what the capacity of Cryptomatte is... It merely came up in my conversation at work. We do not need such features so it's all just talk on our end.

 

The closest I ever came to using such a thing, we didn't need UVW mapping. We simply rendered a black scene by not including any lights and including a Raw Reflection Pass while material-ing what we wanted to change with a 255 red (self illumination material). This gave us the matte we needed, but it was a hack fix.

 

Because I personally rebuild the RGB pass from the elements in 32 bit the hack fix worked out for me, but again, I didn't need UVW information. Your need is very specific so I would imagine your options are limited.

 

Good luck and please post anything you find useful. I'm sure my need is on the horizon and your input will be quite valuable.
