Re: Photoshop and 8/16/32 bit
the idea with 16bit for normalmaps is to avoid having to compress them twice; once to 8 bit (per channel! 24 bits per pixel) and another to dxt5 (1 bit per pixel). obviously compression will only get worse if it's compounded. i usually work in 16bit when dealing with procedural gradients. you can do so much more with so… -
Re: Have i a wrong LowPoly Workflow?
Also keep in mind a 2k texture has about twice as many pixels in it than a 1080p display. An 8k image has 32 times as many pixels as a 1080p display. Down scale it to 2k, you aren't making a hero asset for the movie Avatar 2. It's fine to bake a 4k image and scale it to 2k. Until everyone (including you) has a 4k display,… -
Re: Unreal Deposition/Accumulation shader?
Get vertex or pixel normal world space, get the component that you want (z is up) and use that as an alpha in a lerp to blend between the rock and snow texture. If you want to do this on the normal channel, you may need to recreate the pixel normal, by just transforming your normalmap into world space and then do the same… -
Re: Software that will screencapture to a gif?
The green screen effect is just for visualisation, it doesn't show up in the final GIF. It appears on pixels that don't change for more than one frame, so those pixels don't need to be written in subsequent frames (making the GIF filesize smaller at no visual cost). You can turn this visualisation off by right-clicking… -
Re: Virtuosic's Static Mesh dump thread (U3 Engine)
Yes, you can not do texture like this. Use seperate, tiling materials. Apply them to your mesh with the same pixel depth for everything around the building. Easy way to get your pixel depth (texel ratio, whatever you want to call it) is to box map your entire house at 256, 512, 1024 or whatever you're going for. Then move… -
Re: A simple texture question.
Depends on the system then, I suppose. Vertex alpha blending is usually done on systems with limited amounts of ram and/or video memory. Or it's used as a way to free up video mem for something else. Painting a blend map is ultimately best in terms of quality. It's a per-pixel b&w image that says blend on the white pixels.… -
Re: How 3D model fidelity is usually measured?
your reference point of a 1000x1000 pixel image is really useful. the thing that most artists seem to struggle with is that polycount is entirely dependent on view distance - I'm constantly asked what the triangle budget is for assets and the answer is simply - as many as you need for it to look good at the distance you… -
Re: Baking - where do the rays come from and go?
compute tangent space per fragment isn't relevant here - it affects how data is encoded into the final bake, not how the bake is executed. To try and illustrate how baking works, imagine it does something like this... wraps a texture to the target object, projects a ray out from the mesh for every pixel of that texture,… -
Re: [Designer] HBAO filter doesn't tile?
Ha if the height doesn't tile, then you can't have an AO that tiles. The AO algorithm samples the height far around each pixel to determine the amount of light reaching that pixel, if there is nothing to sample or if your map doesn't tile, it will sample the wrong information and you will end up with a seam. You would have… -
Re: How do they do those incredibly crisp textures ?
Well, i don't really know how to say that. If you zoom on it, you'll see that for instance, a window border or glass, is exactly on one pixel line. When you bake an highpoly, i don't see how you could have that control and be sure that the window border will not be baked on 2 pixels and be slightly blurry. Hard to say for…
