Subject: ummm help with the material room?

hi.

i am somewhat lost ... i remembered doing it - making a reflection on a prop - like a square box - using the material room in poser 5. probably was a quirk...

anyway - could someone help me with it? i have been trying to figure how to set the prop to be a mirror with nice lil reflections and all. i tried several tutorials but nothing is working right...

um. .. thanks for reading :) and reply (if applicable)

are you setting up a reflection node? Stefan Klein has produced a very good FAQ on the Tempest renderer (what Poser calls "Firefly") and addresses your question.

i tried that. ended with patches of dull lines and patches of mirror lines.... very interesting but i never own a mirror like that so that patches are kinda moot.

" i tried that. ended with patches of dull lines and patches of mirror lines.... very interesting but i never own a mirror like that so that patches are kinda moot." This sounds like the raytracer isn't getting enough samples. Try: --Increasing the bucket size --increasing the pixel samples --decrease the shading rate post an example of what you're getting, along with the parameters you're using. Raytrace reflection is, as you know, a very compute expensive proposition. A cheap "fake", when you don't need to simulate reality perfectly is to do a panoramic render of the room, without raytracing on. Then take that image and fisheye distort it in Photoshop (or whatever). . . Now use this distorted image as the environment map for your reflective surface. This will always need a little tweeking, but works well for un-demanding scenarios (if your character is going to reach out and touch the mirror in an animation, obviously this approach won't do. . .but for a still life its fine)

ok ... got a sample to post... without those :

--Increasing the bucket size
--increasing the pixel samples
--decrease the shading rate

why i didnt do that? well .. i was hoping i dont have to, ya see. i dont recall doing any changes on them when i did a good mirror image last time (this time i have to keep a note what i do or i ended up asking the same stuff again)

it's a still life image since i dont think i wanna waste doing animation using poser :)

and yes - there's a glossy thingo there ... i was following another tut somewhere... O_o

Use the single sided square prop as mirror, the double-sided one causes these artifacts. Or you apply a slight displacement to the square, see the link. It should render fine then.
