Lightmap baking problem_new
Hi, I have a scene and just wanted to bake a lightmap for it. So everything for diffuse is on ch 1 in uv and for lightmap everything is unique mapped in ch 2. here is the scene and the baked lightmap, and uv for it. the problem is that I got "spots of light and shadows" in my baked lightmap. it appears to be from the sky… -
Re: Strange Lighting Bugs Even With LightMaps?
The seams you get when having "no lightmaps" aren't actually due to a bug. Without lightmap it will fall back on vertex lighting, but due to Unreals special approach to subdivided vertex lighting, seams appear between modular meshes (which because, great joy, epic by default has hidden the property that is meant to fix… -
Lightmap voes
Hi all I'm trying to make some lightmaps, However, the lightmaps dont show up in the viewport, at all. All the models in the environment has been set to Static, and all the models have the diffuse/spec/whatever in the uvw0 channel, and channel 1 has been prepared for lightmapping. However, nothing shows up in the viewport,… -
Export lightmaps
So it seems that talking about lightmaps is quite popular in this forum, and I'm here to do my part! :) I'm working on a project with a friend and I'm doing the heavy lifting as I have a pretty stout PC. In short, I'm baking the scenes lightmaps, and then exporting them as packages and sending them off so my friend can do… -
Re: How to bake almost perfect lightmap?
Check that your shaders are using lightmaps. Looks vertex lit to me, I don't see any baked shadows. Check that your lights are casting shadows. Check that your meshes have lightmap UVs. Check that your objects are tagged as static. Suggested settings when starting out Lighting tab -> Lightmapping Settings -> Indirect… -
Lightmap makes me sick :(
Hi There! I have troubles with the Light and the Shadows on my little Mesh! :( It makes me sick, because im trying to fix this about 3 Days long.... Getting agressive of this... I tried it with Override Lightmap Resolution, i tried it with a lower and a higer Lightmap Resolution, but no adjustment helped. UV Lightmap: UV… -
Lightwave
i'm quite proficient in animation and modelling with LightWave, but am completely unversed in 3D Studio Max and Maya. i also *own* a copy of Lightwave, and wish to use it to its fullest extent. i'm just wondering why i haven't seen any sort of support for Lightwave recently. back a few years when Half-Life was far… -
Talk to me about Lightmaps.
It's common knowledge that college only teaches you 10% of what you need to know in a professional setting. For my college experience, lightmapping fell into that 90% that wasn't discussed. Unfortunately, it's also a topic that was cited as a weakness of mine when I had my portfolio reviewed at GDC. So I'm wondering if… -
Re: Why can't I get a seamless lightmap even with the most simple geometry?
keep in mind with unreals auto generate lightmap uvs, its not actually doing an unwrap, its taking the UVs from channel 1 and repacking them at a consistent texel density. so if you have stitched/overlapping stuff going on in channel 1 it will carry over to your lightmap and you will get that overlap error. you can do a… -
Lightmap blending with modulate 2x
I've been having a discussion with AlecMoody about adding lightmap functionality to my shader. It's not in there yet, but I'd like to do it. He asked for modulate 2x blending of lightmaps. As far as I understood, that goes like this: Value from lightmap is sampled and ends up in between 0 and 1. That value gets multiplied…
