Ogre 1.8 OglES2 iPhone, Shaders problem with Mipmapping

[jtpsoft]

I've tried with trilinear and yes, no luck with that.

Here's the bilinear version instead:

Ok. Hmm, perhaps I need to revisit the texture filtering code.

[jtpsoft]

If you need some help let me know, I'm not as good as you are but I'll do my best.

Ps: Do you think that the parsing particle bug is related to this one?

[masterfalcon]

Oh, no for sure not. These are two issues. But the particle one might be better asked on the Particle Universe forums.

[jtpsoft]

Actually, as I said, it's not particle universe, it's the ogre particle system. The crash appears during the parsing of a simple particle script, not a PU one. I don't have PU loaded in the code right now.

[masterfalcon]

You need load load the ParticleFX plugin to get that functionality.

[jtpsoft]

The Particle FX plugin is loaded, particles worked perfectly before I updated ogre to the latest trunk. It's something appeared recently.

[masterfalcon]

Strange, I was able to load your particle script just fine with the latest code.

[jtpsoft]

I solved, and that was strange indeed. I create new particles from textwrangler app instead of textedit app and they worked. I guess the problem was some txt format settings. Anyway thanks a lot for the test on your side.

Just to say, I have the same issue with mipmapping, lots of graphical glitches and black patches when I enable anisotropic filtering. Bilinear filtering is what I use instead like jtpsoft, but although the logs says it's generating mip maps (I have it set to 5), it doesn't seem to have any effect and textures still have that grainy look.

Anyway, it's not too important, because anisotropic filtering seems to harm performance so I wouldn't enable it even if it was fixed I think.

Hi,
Im porting to 1.7 to 1.8 on iphone, for use opengl shader ES 2.0, but i have a problem:

When i load an overlay with a material using shader ES 2.0 (not using rrts), crash in Texture::CreateInternalResources() or generatingmipmaps. Any suggestion??

Thank you

[masterfalcon]

Could you give more information, perhaps about the texture. What version of iOS, what device, etc?

[lavz24]

Hi sorry,

I have ios 5.1 and iphone 4 and 4S.

My game crash loading resources, i resolve mipmap problem but crash when loading resources. Dont track trace and not log clues for what happen.

i have a question, all material need shaders?? handleSchemeNotFound doesnt call.

Any tutorial about how to run shader on ogre 1.8 for iphone??

I cant run template model because dont find .h , i modified header path and nothing
