I'm thinking 'one step at a time' but I'll admit sometimes it's better to run before you can walk. Winter@33: Oh, yes, I would love to have that too.

i will NEVER go back!

Low impact greyscale images would be fine. Heck, limit us to 128x128 if you like! If I could do this on the equivalent of a 486 Processor, on a MAC with onboard video...why is it that more than 10 years later, this "can't be done" in SL?

If that's been fixed I'll check it again. About the only thing I use bump mapping for now is the engine intake on my version of Mehve. By the way, folks, you know you can provide alternate normal maps for the Windlight water. Instead of enhancing the bump maps with custom textures, what I'd really love to see would be the ability to integrate the Windlight shaders into objects, so you could set up a ShaderSystem (like a ParticleSystem) with all the Windlight water parameters (except probably reflections) including a normal map to apply to a specific prim surface.

This makes that option mostly useless in high end design and something to avoid using simply because of the minuscule improvement in performance you get from not using it. Inherent bump mapping is basically like saying "here ya go you can only use these twelve free textures we made bump maps of"....but if SL actually tried to, I don't know, get legal license to use DXT we could basically bump map anything we want inherently in the DXT map and to top it off could reduce client side lag by having inherent lod mip maps. I live for the day this platform joins the rest of the development world in the 21st Century. Nice article for the Ivory Tower folks, just the same, I suppose.

It become a feature when it works, until then its a cockup. I should add that to my list of 'features' to be implimented - such as rounded edge cubes, fix the trans-texture error, 'opt in' on group chats (so everytime someone speaks in it - you dont automatically join), PROPER website on a prim and - this ones more 'research' then a feature - customer systems survey - like Valves system polling - it would help you see what systems people own so you can aim for the medium, and if you release this data it could shame people with lower end systems into upgrading.
