Hi,

to optimize my framerate I produce LOD-Steps of my models using
The models are Lowploy-trees with huge 1024x1024 Textures.
I reduce the Texture-size every LOD-Step half the resolution.
But the result was nearly the same
Is it the Texture-size or the number of the polygons, influencing the framerate?

are they dds textures? that should help a lot.

ok..i will try this.... thx a lot!

your tree models SHARE the texture or does each model is saved with the Texture?
i thought about the same some month ago, but i came to this conclusion:
If lets say you have 5 tree models and each share the same texture, why would you need low-res textures if you will only use one?


im 99% sure its the polygons, unless someone wants to correct me.

some hints here:

Thx for your helping tips chris_oat and sivan!

I thought to sharing textures is just possible with textures in the same model.. .!??
I - for example – have one tree with 1100 faces. The textures are 128x512x32mipm for the needles-(sprites) and 128x512x32mipm for the trunk.
There is no possibility to share textures in this model … or I am blind…

To use a group of models as one model makes the “texture-sharing” possible…but with such a group I cannot align the bottoms to the irregular floor of the terrain…

My attempt was to make LOD-steps like tree_0.mdl (128x512x32mipm), tree_1.mdl (64x256x32mipm), tree_2.mdl (64x128x32mipm)…and so on…
But neither with *.tga Textures nor with *.dds Textures the framerate-results are better!
@sivan: but with *.dds textures it looks much better

..and thx for the gamestudio-hints!
I will try to reduce the polygons now … maybe this will work.

you can use external textures for models thus sharing one image among a lot of models.
