Hello all.
Got this situation, hopefully i will describe it well:
- interior, camera overlooking indoor swimming pool, looking through 1st glazed area into the living room (glass pane is 5mm thick solid box), then from the living room one can see outside through big french windows (2nd glazed area consisting of 2 glass panes, each 5mm thick solid box).
now
- outside the house i have a plane mapped with an image (some trees sky etc) which i really need there for some nice reflections and refractions on the pool and other internal specular objects
but
- at the same time, i wanna have all those glazed areas alphaed, as i wanna control the image i have on that reflection pane outside and i will be replacing it and moving in in PS
so thats what i want and here is what i have tried:
basically i have applied some object properties and vray properties to the reflection pane object outside
1st try
max object properties as follows:
- visible to camera unticked
- cast and receive shadow unticked
- visible to reflections and refractions ticked
vray properties as follows
- visible to GI unticked
- visible to reflections ticked
- visible to refractions unticked
RESULT:
working alpha BUT the pool is missing the outsides pane reflections for some reason and it shows only vray sky
2nd try
max object properties as follows:
- visible to camera unticked
- visible to reflections and refractions ticked
vray properties as follows
- visible to GI unticked
- visible to reflections ticked
- visible to refractions ticked
RESULT:
no alpha BUT lovely reflections and refraction of the environment on the pool
DEDUCTION...
i dont get it...if i untick "visible to refractions" in vray properties, how come it affects reflections as well?
AM I MISSING SOMETHING HERE? PLEASE HELP...may be i will have to do this somehow with passes but how?
THANKS A LOT
Martin
