How well does Vantage perform with large scale forest pack scattering?

[kazgaz]

I’d like to know how well Vantage performs when using many Forest Packs and scatters in a scene. I am thinking of trying it primarily for the benefit of quick animation time as opposed to traditional rendering but I do have some quite complex scenes and not sure if it’s worth the investment of time to convert from corona, and go on the learning curve with new software if it won’t handle it very well.

Any advice or tips greatly appreciated.

The engine in Vantage handles large amounts of instanced geometry very well, it is one of the benefits of a fully raytraced engine (vs rasterization). There is a limit of around 16M instances imposed by DirectX, so if you're approaching such numbers you might have to group several objects as one geometry.

Does this limitation mean that it wouldn't make sense to get a GPU with the largest amount of VRAM available? I never used Vantage and I'm in the market for a GPU for it. Heavy exterior scenes. Thanks.

The limitation I mentioned is about the maximum number of instances (~16 million). Memory usage per instance is a separate topic, it is around 500 bytes currently, I think, so up to 8GB for 16M instances, roughly.

Your question sounds more general though - how much memory you would need to fit your "heavy exterior scenes". This includes the size of actual meshes (triangle arrays), texture buffers and so on. It is very difficult to estimate in advance. If you can find someone that already has a decent GPU, you could run a Vantage trial there with one of your scenes...

Get as much vram as yiu can on your gpu. I've run into vram issues with cards with low vram counts.

Gotcha. Thanks.
I'm actually thinking on getting a RTX 5090 on the 30th. It hurts like a mf, but it's probably a good investment, right? I currently have a 1080ti

Definitely...
