hi, I have encountered a most troublesome situation where I wish to have a strict clipping distance which clips all objects at a certain range EXCEPT for one object which must always be shown and never clipped. Is there anyway I can do that?

For the record, the object in question has its z-write disabled because it also must be behind all objects on screen no matter what. Originally this is all that was required, but i added a clipping distance option to the graphics options for people who were having speed problems on slower pc's but this causes the object to be clipped which is a big nono. Think of the object as a glorified sky box if you will.

I've done this before - I have a skybox 10 units in size per side and keep it centred on the camera. It also has zwrite disabled. It works just great for me.

I tried it but it unfortunatly caused a series of its own problems where things depend on the cube keeping its size of -1000 -1000 -1000, tons of precalculated locations and stuff (it isnt actually a skybox, but can be thought of along the same lines)

What i really need is a way to tell darkbasic to ignore the clip distance for this one object and draw it regardless :/

the problem is I have a 9000 line engine which has many many many refrances to this object which depend on its current size. For example the texture for this object is dynamic and represents a graph which starts looking odd when the object size is changed even when its positioned at the camera point :/

I did try though - i will fiddle with it somemore and i can probably get something acceptable up - but this really isnt optimal, it really should be excluded from the clipping system

Thanks for your help though btw, dont mean to sound unnapreiciative XD
