Hi,
I guess I should make it clear right away that I know little abut Sketchup as I gave up using it years ago, and just started to use again (SketchUp 6.0, i was told that would be the best version, although it's not the latest). Also, since i know little about creating objects and exporting them, I'll probably use bad terminology and stuff.
So, the scenario: I'm working on a BTB project that could do with some building objects - besides the ones already available in the downloadable XPacks. I thought I'd try converting some freely available, pre-made SketchUp building models, thus saving all the time and work of creating the models myself. Downloaded some such free models. Following a video tutorial (and common sense), I converted the models into .dae so that BTB's XPacker utility can recognize it. With XPacker I could create an XPack of the object that i could open in BTB. Fine.
Where's the problem? - you might ask. The answer: with the texture files. The XPacker tutorial videos all point it out that the texture files must have dimensions the powers of 2 (2, 4, 8 etc...). The prefab Sketchup models have texture files of different dimensions, of course. When I load the model in XPacker, I get a notification that the texture files are not of proper dimensions - but it still lets me progress and creates the Xpack.
Question #1: Do i absolutely need to have texture files with dimensions that are powers of 2?
I would certainly think so - but when I opened the object in BTB, it seemed to have all the textures just fine, although they were still of improper dimensions. In BTB the building seemed as fine as it should - but when I exported the track in rFactor, some of the textures of the object just didn't render: half the building was simply invisible (although it wasn't the case in BTB - all the textures seemed to render fine there). What puzzles me is that the other half looked OK. so, it seems as if rFactor had only problem with certain texture files, rather than all of them.
Question #2: If i have to resize the texture files, what size do I resize them to?
For example, I have a 645x320 image. Neither of the sizes are a power of 2. What sizes should I choose?
Bonus Question: does the image file's type matter?
Sources often say it's best to use .dds files. But, right now, I only need my objects to be usable and to render properly - at this point I don't really care if the textures don't look the best they could. It's enough for me that they render and in the right size/place. Should i still convert the .jpg files to .dds then?
I hope these questions make sense... If not, just ask and I'll try to provide answers.
