Re: The cost of a texture "draw call"? (Quantity vs Resolution)
@Geosmith "Still though, understanding how much is this draw call worth in terms of performance is still an issue. But if they should have a fixed cost per draw call, then surely there's an average amount of draw calls per frame for games that we could find? Comparing how much a typical scene or asset would need would… -
Re: Curvature map, Ambient occlusion and thickness map
I think that Sobel math style "rate of change in normal direction across <n> pixels" is what causes seams issues working in UV space . in Blender you could just do dot product with world space normal map ( Considering the world space normal map is baked as direct output (emit) with -1-to-1 scale ) It gives same edge for… -
Re: Maintaining the suspension of disbelief...
was talking with a professor about something similar the other day. he had been reading up on some articles, one in particular concerning Beowulf, that the closer we get to creating perfectly realistic interpretations of life, the further we get from believability. but then we cross that line and reach that perfect combo… -
Re: Maya 2019 UV/polygons issue
First of all you should not have overlapping UVs in your 0-1 UV space when baking, you should offset the overlapping shells by 1 in U or V (This is not moving them to another UDIM either, games rarely use UDIM workflow anyway). Moving the overlapping shells across basically mean they will be ignored when baking. Each pixel… -
Re: How would I go about UV mapping this?
Depends on the app you're using. If its max2012, probably explode by smoothing groups and then stitch and rearrange, or a lot of select by planar angle and quick planar button. Or Planar map the whole thing, select the edges you want to be seams, break and arrange. I agree that working on it in pieces is a good idea, in… -
Re: NormalMap baking issue
I agree with EQ 100%. He saved me having to write up the same thoughts :D You should also realize that it doesn't matter how accurate that cage is, getting a detail that looks that "high" is very unlikely. Normal maps are great, but when you look at the detail at a slight angle it isn't going to change in silhouette… -
Re: Annoying white outlines after rendering
However the hair system works, it is probably using a texture that has alpha. The first strand is drawn which the edge is .5 hair + .5 white skin. When another purple hair strand renders UNDER that one, the previous blended hair has already been written to the screen and determined to be closer, so the hair underneath is… -
Re: Low quality normal map Substance Painter
You get "blurry" result because 1 you waste the 70% of the texture space on the overlapping planes 2 you are trying to put edge softness from a 4k texture on a 60meters big object. so you have very low pixel density (about 70 pixels per meter). To fix the mismatched smoothing-uvs, there is generally one rule... Whenever… -
Re: Advice on details for a cylindrical object
My understanding of normal maps is that you shouldn't treat them like textures, they're mathematical values that were calculated, so if you go through and just overlay blend new values on top of them you aren't going to get the correct result of each pixel color because overlay blending isn't the right math formula for… -
Re: VR recommended font size?
There is nothing like "font size" in VR except something you would compare to real printed text. You have to think in a way like holding a page of a newspaper in front of you. Can you read the text on it? No? Then you need to scale up the font. It's font height in relation to distance to the viewer. One thing you have to…
