Kurok: shivering weapon model

[domis4]

Hi, i do for fun some BF3-stylish weapons for Kurok.

After some finished models( which worked fine on fitzkurok on PC),
i choose to give them a try on the PSP. All of them are between 700 and 900 Tris.
The Texture is 480x something. Exported using Blender's 2.69 latest Quakeforge Exporter.
Totally there are 20 frames and as said, everything works fine on PC.

After packing the models to the PSP, there is a constantly shivering.
Best you give it a try: http://www17.zippyshare.com/v/25431406/file.html

is there a solution for this problem? because its freakin annoying while playing

EDIT: it doesnt look like the common mdl "Poly-Swimming", its really shivering

Skin is too big for psp, use 256x256 (or 128x128 for Phat to save ram ) and it will be fine.

[domis4]

first, thank you for the really quick reply.

did it immediately, transformed the texture to 128x128 but still the same shivering.
Even a fresh kurok pak file didnt solved the problem.
Ive got the PSP Street aka E1004, afaik it has equal specs as the phat. (except wifi)

[drm_wayne]

can you make a screenshot? i dont use kurok on psp.

[domis4]

sorry, but you cant make a screenshot of the shivering
unfortunatelly i havent got a recording software.

[drm_wayne]

why not use quakes internal screenshot function??

[domis4]

thanks, didnt knew that

well, its not realtime captured video, but you get the point:

ignore the camera shaking, its just the shivering of the model

[drm_wayne]

looks funny, but idk whats happening there.
Im my PSP engine i dont have such effects.

I've never done anything on the PSP, so I can't test this or offer much help. Does the PSP require power of 2 texture resolutions? Maybe you need to use a 512x512 or 256x256 texture instead?

Edit: Somebody beat me to it (that's what I get for leaving random forum windows all open).
Edit2: After looking at the .gif, it does not appear to be texture related at all. Does the weapon have some sort of idle animation where it moves slightly? Have you tried simpler geometry/no animations?

Yes it uses power of two, if you use 80x80 it will be upscaled to 128x128 etc...
Since he uses Kurok he should only use 256x256 OR 128x128 since Kurok doesnt have DXT Compression.
I think his problem is maybe the v_idlescale OR the analogpad input (change the values).

@jitspoe:

thanks,

well, it propably is engine dependent. at a closer look, every kurok weapon (even the original one) shivers.
The original ones are further away so, you cant see the shiver that much. but i made them to match the ironsights.

@drm_wayne,

which engine did you use, and/ is it compareable to kurok? (smooth model animations, smooth lighting, iron sights)

i tried different values (even disabled analog) but it didnt affected the shivering, so only v_idlescale is left?

Looks some sort of woobling, maybe due problems when generating float point vertices from byte-precision data ? I don't know PSP, it's just a wild guess based in the animation.
Maybe if you could make one of the models available to download we could examine it and have a better diagnostic.

[r00k]

is it possible in QuakeC you have extended frames in your animation loop?

[domis4]

Sry, haven't looked the last week at this forum, so here are the Model files:
http://www18.zippyshare.com/v/18606795/file.html
the zip contains the vshot.mdl and the vnail.mdl (the Pistol and the Rifle)

[drm_wayne]

If i remember right Kurok has its own custom functions for the first person weapons, i just played it again and they look and act totally different than in vanilla quake..
maybe just disable it in the engine or copy/paste it from vanilla quake.
