Re: UDK Newb Questions: Lightmaps & Geometry!
Hey guys, I have another newbie question regarding lightmapping. If a really small prop uses an 8 x 8 or 16 x 16 lightmap, how much spacing between shells is needed for those? Is the general rule 128 x and above 2 pixels; and anything lower than 128 x would be 4 pixels? If i were to give a small prop a 16 x 16, should I… -
Re: photoshop brush tool... w/ size scaling
Bit of an old thread, but I stumbled on it after doing a search for exactly this problem. What I don't get is why nobody appears to have noticed that it also does this when using the brush tool. Try it - choose a 5 pixel brush with just size set to pen pressure. When the brush reaches 2 pixels in diameter (well, 1.5 I… -
Re: Vertex colour = Gouraud shading?
So it would be multiplied at a pixel level then right? And all in 1 render pass, simply altering the colour of the diffuse pixel? Not having pixel level control in my engine is pretty annoying. I'm contemplating adding Vertex Colour, but it's going to be too expensive, like Gouraud Shading. Both involve rendering the… -
Re: what exactly is an environmental map?
I wouldn't say dead wrong, just incomplete. "imagine the envmap containing a sphere"? That would confuse me. I'd say instead that one should imagine the envmap being mapped onto the inside of a sphere. When you have a model that has an envmap reflection, each pixel of the surface has that imaginary envmap sphere centered… -
Texture Question
I am trying an art test and I have been given a limit of "Texture Limit: 2 1024x1024 texture sets (or equivalent texture space) including seperate diffuse, normal, and specular. Note that since these objects can be close to the viewer, please maintain a pixel density of at least 1024 pixels per 3 meters." The pixel density… -
Re: Early-Late 2000s CGI/Game textures
For characters were out of my skill level, but for environment work I used some of these techniques: - Photo sourced; either I used a library we had in-house or used photos I took myself. - Photoshop to desat, fix lighting, make tileable, color correct.. needed a good base for the next stage. Depending on the texture it… -
How to pack more details into my terrain?
Hi! How do you pack more details into larger terrain meshes? Lets say I want to build moon like terrain. 500m x 500m area. If I texture it in Substance Painter with 8k PBR materials I get about 16 pixel per meter resolution for color, normal maps. If I look it at close range it looks pixelated, not so bad, but,... I cant… -
Re: Why after so many years Painter still doesn't have an adequate "roll" brush
oh, sorry. I forgot about lazy brush button . Thanks a lot Jerc. A lot better when lazy mouse is on but still not as pixel to pixel crisp as in some vector editors. And set up is really painful. I loved "skeletal" strokes from 25 years old "Expression" vector editor. You could simply add 10 pictures to a vector stroke and… -
Re: UDK lightmaps
Thanks for your answers guys :) The actual mather is : if I snap on a 30 pixel grid it will be ok with a 32 pixel lightmap, but if I want to enhance to 64 or 128 it wont match, I'll have to redo my UVs. I need to have multiple lightmaps resolution choices (low res for background instancied object and better rez for the… -
Re: Hi I'm looking for a height map of an real life terrain, to create a terrain out of it.
Photogrammetry with drones works quite well and it's commonly used for medium to low detail capture (up to a couple of metres per pixel). I would imagine there'd be a fair bit of trial and error involved and it could get quite expensive - not to mention time consuming - but it's a valid path to follow if you have the…
