Typical IVA texture resolution?

[jfjohnny5]

I'm working on the IVA for my 2K Command Pod. I've finally got all the UV mapping done - in that all the geometry has is unwrapped and set. Now I need to decide how to lay it all out. I did the external with a 1024x1024 texture. But there are so many components on the IVA. I feel like I need more room. How common is a 2K or even 4K IVA texture?

I wouldn't recommend going any bigger than 1024x1024. Remember that memory usage scales up exponentially with texture size so 2048x2048 will take up for times as much memory. You would actually save memory by splitting the objects up across a couple of textures.

That being said, I've made IVAs for similar sized pods using a single 1024x1024 sheet. It's important to consider what areas of the internal space the players will see a lot of and allocate texture density accordingly.

Though, when you make the textures, isnt it a good idea to make it on a larger swatch since you can always scale down the resolution in unity? for instance, making it on a 2048x2048, but writing the part to have a texture resolution of 1024x1024?

Personally, I'd recommend 512x512, as low as possible.

Here a little comparison between 512x512 (Downscaled from 1024x1024) and 1024x1024 on my own Gemini IVA.

You can save a lot of texture space by spinning things off into props, plus you can re-use them in other IVAs

512

1024

So, it is the little things that suffer really, the chevron stripes get a little ugly and some of the "panel" lines get fuzzy, but overall - depending on complexity of the IVA scene - 512x512 is okay, IMO.

Of course, this is a really basic IVA scene, for something like a station part or lab, absolutely go 1024x1024 (But, I wouldn't recommend higher).
