Hi Andy,
I'm sorry to year you had a crash.
Is there anyway i can point L3DT to the LM.mmf to continue just rendering the textures...it was the calculations that took the most time the textures only would of took a few hrs.
Yes. The completed lightmap should be listed in the project file, so L3DT should still load the lightmap. If it doesn't, there are two ways to get it back. The quick way is to manually edit the project file using notepad. Under the 'maps' list, enter the following section:
- Code: Select all
<varlist name="LM">
<string name="Filename">LM\MyMapName_LM.mmf</string>
<string name="MapType">24bit</string>
</varlist>
(where you change 'MyMapName' to the appropriate map name).
Alternatively, you can use the 'File->Import->Custom map layer' option. Here, select the MMF file, set the layer name to "LM" and the layer type to "BYTE[3] (colour map)". This option will be slower than the notepad path above, because it involves the copying of the map data.
- Code: Select all
What i mean is...are the calculations saved in the LM.mmf, or done on the fly.
The calculation
results are saved, but no other calculation state information is saved because it would make the process absurdly slow(er). Thus, a calculation can't be resumed if it stops part way through a map layer.
- Code: Select all
At the moment im sitting with map15_LM_x127y63.bmp as the last texture done, with all the textures weighing in at a whopping 6gb
Wait a second...I thought you said the light map calculation was finished? If the light map tiles aren't all there, the lightmap calculation didn't complete. The lightmap calculation has two parts; the first generates a shadow map, and the second uses the shadow map, the normals, the water map, etc to generate the light map. The light map tiles are saved in the second stage. If that didn't complete, then I'm afraid the data is lost.
At present the shadow map is not stored for later use, although I think I'll now change that for the next release so that you don't lose it if the system crashes during the 2nd stage (
now on the to-do list).
I've also popped the 'calculate light map area' option onto the top of the priority list, and I should make a start on it in the next few days if the winds are fair.
Best regards,
Aaron.
