yay. painted my first texture ever. one of many to come!
very simple piece of stone work. Does this look like stone?
The texture is 2048x2048
will I run out of space with textures that size?
What is that supposed to be? It looks more la some dark grey metal or concrete, and you can quite tell apart the tiling, even though the texture is so large and the object itself looks fairly small.
For one, you should get rid of the light/dark value differences. You need some for the darker areas, of course, and also some slight variation.. but in your texture you got big dark spots that are what makes the tiling texture so easy to tell (ie. you can see it goes from 'light' to 'dark', then light again, then dark, then light, then dark).
You also need to work on the material itself (spec and normal) to make it look more like stone or whatever you are aiming for.
Oh and yeah, 2048x2048 for an object that doesn't seem to be that big, seems like a waste. It all depends on what the prop is, and whatnot. But if it's some sort of support frame, you'd like to add some wear details, etc.. and yeah.. take the texture size down most likely
Again though.. it depends on the scale of your level, how are you using that prop, etc.. there's no pre-made sizes and polycount.
