shifting textures

[svenip]

are they projected or real UV textures ?

if projected, make sure they're connected to the motion of the object (parenting etc...)

[alexx]

correct me if i am wrong but planar mapping is a projection or do you mean UV mapped?

btw: viewport and rendering unfortunately is not really something that is 1:1.. even with exprensive gfx cards.
so better rely on IPR when tweaking textures.

can you send a pic to show the look of the problem?

cheers

parent it to the object.

just select the projection, shift select the object and press "P"

btw : where do you study in germany ??

Ok,
I'm a bit confused now and unconcentrated since the last 3 Days.


I think I become slowly older ! ;-)


Must I realy parent the projection to the object ? Also, when the object isn't animated ?

just select the projection, shift select the object and press "P" is sure, but it doesnt work. This is the message: "Error: Not enough objects or values." Is there another way to parent ?

I cant render with IPR becauce i wish to raytrace.

any Ideas, again ?

thanks

[svenip]

so let's help.

of course there are more ways to parent. just drag the projection in the outliner (with middle mouse) onto the object. voila.


if your objects are animated you definitly need to parent the projections. if they're not animated, you don't need.

IPR is for pre rendering. so no one needs raytracing for pre rendering. just turn it off for ipr finetuning and then on for final rendering.

[YellYellYell]

No, its not working.
also not with the parent(ing)


any ideas ?

[svenip]

come on, give us a screenshot of your scene (with outliner, everything open)

[YellYellYell]

here are one example of the problem.
The shifting depends on the distance of the camera.

the first picture is a render of the normal perspective,
the second is a nearby camera render and
the third is a distance render with the same camera.


nothing is animated !

any ideas

[alexx]

ok.. for me the time has come where i want to see the scene file.. can you make a small one with just that picture (and a jpg as file)?

hope i can come to it before i leave for christmas :)

i wish you all nice days if not and a happy new year

cheers

:beer:

[alexx]

as i see the pics.. you dont really use a projection for mapping that image?
but even if so.. it should work..

hmmmmmmm
strange

[YellYellYell]

Hi,
Here is a small szenefile.

www.medianer.de/matthias/stupid_camera.rar

Move the "incorrect camera" in the szene and render it.
So you can see the render problems.
The textureproblem depends on the position of the camera.

Please test it and give feedback.

You can see the render-results of the different cameras on the image.


I have no idea !

I need help

thanx a lot

[wrend]

probably need the textures w your scene,

but on quick glance id say its your clipping planes that are wacking things out. try keeping them in the same range as they come 0.010-1000.000 ...so if you adjust front to 0.001 adjust far to 100.000. maya'll have probs w float precision on depth if its got crazy distances or strange range between its clips. not sure if your apterture changes may also be influencing this. interesting that the other box you tried it on didnt have problems. was it a different processor type?

[alexx]

yeah.. from what i see i would say that it is your camera settings as well..

i think a clipping plane from 0 will bring maya deep into trouble..
and the other values as well..
i cant point my finger on the problem - might be that some of the camera values cause the problem.

i would suggest using a new camera that has more "regular" settings..
as we all know maya is not really the best in handling units :surprised

cheers

alexx

and yes: i would really like to know what happens, that another machine renders the pics fine.. really (not) funny

[YellYellYell]

hi,
I must use this camera, because its a part of an 8-camera-setup for a special virtual reality display system.

I have to test it again on another machine. But I think I made a fail. I dont think it works on the other machine.

Here is the texture, I forgot it.:rolleyes:


damn, I need this special camera settings:thumbsdow

do you have any other ideas ?

[wrend]

you cant change the clipping planes? those values were given to you explicitly? aperature i can understand, but those clips?

[YellYellYell]

yes sure, I can change these settings, but I tested it and there is no change.

Did you test it too ? does it work on you machine ?

[Boolieman]

Have you tried to put the shader on certain faces? This will help with the location i think and i think that is waht your problem is.

[YellYellYell]

sorry, I dont know realy what you mean.
could you describe again.;)

Could you test what you mean on my szene file and give feedback?

I hope its that what you mean, because I realy need the answer of this problem.

This absolute necessary for my diploma.:rolleyes:

:wavey: HELP ! :wavey:
