I'm currently doing the art for an isometric game for desktop. Since the assets are pre-rendered and not pixel art I'd like them to be in a higher resolution to have some detail.
For Example: I f I render my tiles in 256x256 there are already some details lost, so I'd like to have them in 512x512. Would that cause the tilemaps getting to big?
And how should I go for animated sprites?
For Example: I rendered a spritesheet with a character walk animation (25frames, 8 directions) in 256x256 (again I'd rather like to have 512x512). This spritesheet is already 6400x2048. That seems to be pretty big to me. What size should a spritesheet be at maximum? 4096x4096?
Is thre a way, to use this higher resolutions or do I have to use smaller images and live with the lost detail?
How do you handle this in your games?
Thank you for every advice.
