this is the first picture i used a self made model in (you guessed it, the ball;) ) and i'd liek to have C&C. but, when i wanted to render it in 1024*768, it would take me 11 hours! (on 640*something it took me about 3 hours) but can someone explain why it takes so long, is my model too big? (i don't think so, though) well, anyway, what do you think?

Vue (and not only Vue!!) needs lots of time to render all reflective material like glass, water, metal... That's normal, it's not just you. :-)Guitta guittalogo.GIF

yeah, but don't you think 11 hours is a bit much concidering it is such a small object?

No, all depends of the render settings and the image resolution:-). Ask around here. Some of us render 2 or 3 days -and more- an image. Guitta

depends also of th number of light. Recently I tried to make a test with only one reflective sphere and one reflective ground, the scene being surrounded by an hollow half-sphere with a mapped image, with 16 soft light : should take more than 40h in 640x480. That's why the test is a little bit delayed ;=)

One way to speed up glass is what the refraction index is set to. As the material setting gets higher toward crystal and diamond it's going to slow down much much more. To speed it up more try setting it closer to 1 but not one but try setting it lower that you got there. Lower than even normal glass if it's solid.One more way is avoid solid glass and make it a bubble shape instead with Boolean difference. A smaller sphere within a bigger sphere. That will also speed it up. Grouping propeerly helps lots too. Just do a search for grouping on this forum for posts by me. I've explained it lots of times already how to do it for maximum render speed. The computer speed has lots to do with it also. Slow computers take longer of course than faster computers. If you have a fast computer than your doing it wrong. Look above for it's solution, it works. You can probibly cut it down to 5 hours or less if you tweek the scene a bit. One other thing too if you don't need absolute perfection Broadcast quality gives usually excellent results. Like there is no use waiting 11 hours for something to render then converting the picture to jpg format. It's counter productive. The resulting jpg image is worse than a broadcast render.

but what do ya'll think about my render? :P

It's a little grainy. Should have a finer setting (broadcast or more) but you know about render time. What's the title of the image? I don't understand why the glass ball is in the field? Maybe I have lot anough imagintion (LOL):-) Guitta

dunno a name yet, a friend came up with the scene (a field with flowers and trees and a ball full of dark stuff) so i decided to see what i could make of it maybe i'll call it the second sun or something cheesy like that:D

BTW, only render images in 1024 when you really think they are GREAT and keep the others in a smaller format. Here at Renderosity we cannot see in ther wholeness such images, anyhow. 800x600 for Renderosity is fine. So, don't loose your time in rendering with not finished images either or just do partial renders. And as MightyPete already said, you have to compress images for upload here, it will loose quality. This makes not worth the long render time:-) But you will discover by yourself. When I was new in Vue, I thought I must render every thing as big as possible LOL. It's so fantastic to see an image on the whole screen:-) Guitta
