Re: Does anyone know AI way to turn a piece of google map into hi res and hi detailed terrain image?
it doesn't get any better than about 15/20cm per pixel even if you're buying it off Airbus - the difference is that the online services are all pretty heavily compressed. if you're drawing round these things you need to be conscious of the CRS that the data is displayed in - the further you get from the 'origin' of that,… -
Re: Does anyone knows how extract curves node work in substance designer?
Thank you poopipe I recreated your way step by step and still see yellow triangle and no curve in SD :# . As always Substance Designer does it most crazy, cryptic, monstrously inconvenient way ever possible. No hints whats wrong , zero explanations . But I am not surprised at all , their nodes are generally same . You… -
Re: Maintaining the PBR workflow
The reason charts of roughness values vary is that you're defining an average roughness value for a pixel and that value will depend how large an area of a surface the pixel defines. Eg. Sandpaper is quite shiny if you look very closely but if you step a few paces back it looks much rougher cos the lumpy surface bounces… -
Re: Undead Fat
here is your problem, you are trying to copy the concept pixel by pixel while ignoring the high level anatomy. before you take the concept too literally you need to have a model that looks anatomically sound. once again this model is at a stage where i couldn't provide a single paint-over to show you the flaws because… -
Re: [PBR] Physically Based Rendering Bible
I never fully understood why people say that with a metalness workflow the specular reflectance has to be hardcoded. For instance, I am working with the PBR Plugin Alloy for Unity which also employs a metalness workflow. It is based on Disney's Principled BRDF. However, you can still assign a monochrome specular map. That… -
Re: Texture Leveling
lets go deeper. gamma 2.2 isn't actually a pow(color,2.2) function. the suggested way to convert to linear space is: "RGB = ((R'G'B' <= 0.03928) ? R'G'B' / 12.92 : pow((R'G'B' + 0.055) / 1.055, 2.4))" followed by "Luma = 0.2126 * R + 0.7152 * G + 0.0722 * B" The ' means prime, and implies that a color is in gamma space.… -
Re: UDK --> tessellation
Woah, resurrected thread! I have made a ton of progress since then. Looks like tessellation and displacement mapping are not the "make it look pretty" buttons I thought they were going to be. You have to be extremely careful with texture stretching. Another huge pitfall are mesh seams. These will happen on UV shells when… -
Re: most games are not becoming better!!!!
Right, people often misconstrue what a normal map is, because of poor associations and lack of creative thinking. Most games that have normal maps are the bleeding edge hyper-realism games, so thus, normal maps = hyper-realism. In reality, a normal map is simply a method for getting more accurate per-pixel lighting.… -
Re: AO bake has zig-zaggy artifacts with clipping geometry in Blender
Could you post your UVs and the baked AO map? The jagginess is most likely from rotated UV islands, or at least edges on them that are not completely horizontal or vertical (no rotation). If you take care to align your UV islands better you should get rid of most of them. Another cause for the edge brightness could be UV… -
Re: New Portfolio Piece - Torowyn's Rocket Tower
I would try and do night lighting on this. Might work out pretty well, Soft light blue for the dominant light and then make some torches and scatter them around and use them to control the composition (or what ever lightsource you feel is applicable) This way you can do nice soft fill lights into the shadows to get them to…
