Hi all!
I'm back! This is the number 1 and only problem in making my models, and thus, it makes my 3D buildings black in some parts of the day, because of a faulty lightmap, could anyone teach me how to do this? and also how to add night textures.
I am building my models via Sketch up 2015, exporting it as .3ds, then converting it to .ac in ac3d
Thanks!

If on windows just open in paint and save as .png
If you want to convert a set of images use this

Why convert to .3ds? you can save the skecthup model directly to .ac using
this plugin (double sided version) and here the
same plugin for single faced objects"about the app of SHM" no need to install anything, if you are using Windows, open the jpg image with Paint and save it again but under PNG format, you will save some disk space. Under Linux, Mac you have a similar method Just like SHM says
"About black faces": you can directly edit with Notepad (or similar) the .ac file (no need to regenerate the file again) all the material lines with black faces (something like "rgb 0 0 0") replace with this:
Code: Select all
MATERIAL "MATERIAL_NAME" rgb 0.72 0.72 0.72 amb 0.8 0.8 0.8 emis 0.08 0.08 0.08 spec 0.2 0.2 0.2 shi 128 trans 0

For the first reply,
SHM, I have tried that already, but with no luck, after I converted it, there is no texture shown, it becomes white.
I'll try to do it again within the week since I have a new hectic schedule at college.

Are you able to see the .png properly?
Then try this:
