Question about material conversion and octane proxies.

[Timmaigh!]

Hello there,

i recently got some foliage models to use for my archviz renders, in 3Dsmax format, set up with Vray materials. So i needed to convert the materials, which i did with the built-in max plugin convertor. I would then save these models as a new file, to still keep the vray-rigged version, in case i needed them in the future, for whatever reason. Here i found out interesting thing, these newly saved files with octane material are often quite larger than the original file. Like 50MB file growing to 180MB. Which is not great.

My question is, any idea, why is this happening? I presume its something concering the modeling app, but its not result of the material conversion, right? It makes no sense that octane materialed model would be 3x as big as one with v-ray. But what do i know...

The other question i have, does using octane-proxies save up vram, when compared to simply instancing the model as is? Or its only useful to improve viewport performance in modeling app, as the proxy has usually fewer polygons than the standard instance, but their vram imprint is the same?


Thanks in advance for your responses and help

Hi Timmaigh!,
To better understand what you're referring to regarding the conversion, it would be helpful to review the original material.

Thank you, i checked the link, but it still kind of does not answer my question, which is what is the benefit of the proxy? Cause as far as i am concerned, regular instancing already does, what proxy is claimed to do, in other words saves filesize/vram.
I tested this by loading one flowerbush object into Octane standalone and the vram used was 2,01 GB. Then i loaded scene with 3 of these flowerbushes (original object + 2 instances) and the vram used was 2,22GB. So is this relatively small increase compared to the vram footprint of a single such object (but still an increase) in size what would i would get rid off, if i used proxies instead?

I am currently in process to make my renders better by obtaining some nice foliage models, but they are rather big and in my last scene i did hit the vram limit, when i tried to use too many of them, so i am trying to find a way to improve on that, so i dont have to make compromises or downgrade in quality next time.

Thanks again
