 |
|
Error trying to lightmap with the following features:
3 lights
Lightmap size: 512x512
Individual textures minimum size: 512x512
Individual textures maximum size: 512x512
Number of (blur) filter passes: 1 (happens also with it set on 0)
Generate shadows: yes
Consider non selected objects: yes
Bake scene ambient color into lightmap: no
Normal auto smooth crease angle: 0
Error message:
Access violation at address 00406770 in module 'deled.exe'. write of address 07170010.
After pressing cancel another error:
Access violation at address 0055C8B0 in module 'deled.exe'. write of address 00000064.
It only happens if I choose an Individual textures minimum size between 256-512 |

I tried the settings, no problem here. One advice though:

Lightmap size: 512x512
Individual textures minimum size: 512x512
Individual textures maximum size: 512x512 |
That's not how you use the lightmapper. It just makes no sense. With that setting, for every polygon, no matter how small or big, will be created a texture file. You don't want 5000 bmp texture files.
Plus, every polygon will have a lightmap with 512 size, the ones that are very small and the ones that are very big as well. It's not efficient at all. You should set it to about 8 or 16 for minimum and 32 or 64 for maximum size.

| Did you maintain an even polygon resolution, or do you have giant polygons all over, and odd sizes everywhere? |

The polygons are not weird, pretty squary.. I still haven't united all objects together though I'm afraid that when I do I'll get weird polygon sizes.. |

| They look smooth to me. That is exactly the shadows I would expect on that model. |

There's a rough visible grading between the shadow colors from the brighter to the darker parts.. something I didn't get on 3dws, I want to reach a better level?
lol, thanks Fletcher |

Because you have a flat white texture under it. That will go away when you have a real texture under there. This limitation is visible in every tool, it's just what happens when you only have 8 bits per channel.
Try setting your smoothing crease angle between 45 and 80. Just as long as it's not 90, that will kill the edges on your boxes.  |

Well I guess you can just have a save with everything in white until then.. |

| Just wanted to add that I too like that model very, very much. It's one of those models that I can't imagine improving with texturing because it just looks lovely the way it is. |
