Does Image> Size do anything?

    In the texture>edit interface, there is a section titled "Size” which defaults to Width 512 Height 512. I thought this might resize the texture, but as far as I can tell, it does not. It doesn’t appear to do anything. Am I mistaken?

    Hi Adam, unfortunately you are right and those inputs do not change anything. I believe they are a relic from an old feature and should be removed.

    It would be useful to have the ability to down-res textures within Threekit. Upload 2k, experiment with 1k, 512 to see the quality & memory footprint difference. (My goodness, the memory footprint difference between 2k & 1k textures!)

    By the way, is there a tool that shows VRAM footprint of a given model/material/scene? Such a tool saved my bacon on another web3D platform.

    In my ideal world, I could query the user’s device how much VRAM it could make available, and down-res textures on delivery. Having to deliver every user the least-common-denominator asset is a real pity.

    There is not a tool built into Threekit for that but there are some docs on best practices to achieve good performance and a high quality visual.

    Those are interesting ideas - if you have other thoughts you can post them in #platform-admin:feature-request. No promises on an implementation of course but I like to get perspective from users and can raise my hand internally.

    Yeah, I’m sure getting client device information is far, far, outside the scope of what Threekit could do. That’s more like "let’s have Khronos & Google to update the webGL spec” level! Probably opens a nest of vulnerabilities, too, but wouldn’t it be nice?

    Just discovered: the Size setting does have a function on a Canvas, to specify its resolution.
