Depends on if you desperately need any of the new features because once you start working on adding/editing the ved in 5.x you won't be able to go back & use the same ved in 4.2.5 anymore. You would have to use an older copy or backup copy of the ved before you swapped to 5.x. You'd also have to recreate whatever you had sorted out while working on a ved in 5.x.I would like to use VS 5 especially to be able to export the demo (and later the game when I buy the mobile license) to Android and IOs (in VS 4.2.5 I had some problems and did not work well the compilation). My fear with VS 5 are some of the bugs I've been reading...
As for lightmaps... not sure. 25% of scene size should be fine.
what do you mean by "doesn't work properly" ?When the character moves to a dark zone of the scene, this is darker than shown in VS 4.2.5.
... and that only on some scenes?The truth is that it's really strange...You could test it out how it should look like by open your character graphic in an image editor which has layer abilities, also open the lightmap. Pick from there the dark color and fill a new layer at your character graphic with it. Then set this layer to "multiply" as a blending mode. This should represent how the char will look like ingame when in a dark spot.
Now, I deleted those transparencies and all work fine! I think the maplight must not have transparencies...Hm, but in 4.2.5 it is possible to use f.e. 50% or 80% transparent light maps. I often have smooth borders (what means transparency is going from 100 to 0%).
