hello everyone

well, i still have a torture with camera mapping....

i try to project textures from three side - front, left, right.

so, i have three cameras, which projects textures on geometry.

and i have main camera, from which i looking on my object.

I want the requisite texture downloads in definite space

for example:

if the main camera situated in zone of front camera - downloads the texture projected from the front camera

if the main camera find oneself in zone of left camera - downloads the texture projected from the left camera

i have done some experiment with simply geometry , and i suppose that solution hiding in the switch sop (switched between camera prijects).... may be i must write any script in SELECT INPUT???

i'll try

i whant to flying around the big ben tower

that is why i need to project four textures on four side of tower (from four cameras)

how can i do that? :ph34r::ph34r:

You can map each face of the tower separately, there's no need for camera projection (you can specify primitive umber in the UV texture SOP).

Yes, ok! But why you need switch cameras for that!? Four cameras, four projections? As digitallysane said this can be done by simply projecting as many textures as you'd like on geo deviding it with groups or using LayerSOP.

You can also specify as many projectors as you wish in the same time!

cheers.,

well, thank you

.... give me please an example where texture projection from camera (from many cameras) is irreplaceable

my goal is TO TEACH this technic.

especially projections from many cameras, not from single.

i deside to project texture on big ben, probably it is not good example.
