reflective ground in pro

Unity Engine
1

hi,
im still new to unity and i have a question

i made my ground object and assigned a reflective/bumped material to it. i have the textures and i have my alpha channel.

from all the forum answers and research i know i need to create a cubemap so that the ground object reflects the many tables, chairs, ceilings etc above it.

How do i do that? please be gentle as ur explaining hehe, thanks

with whatever program you want and you can do it.

From within unity, there is no such functionality, thats work thats done on the artist side outside of unity

thanks for the quick reply

so let me get this straight… i need to somehow add the tables chairs of the scene into a cube map that the ground’s material will reflect? and all this outside of unity? if yes then can maya do it? and how?

isnt there some sort of command that tells the material to reflect the stuff above it? or create a cubemap from the scene itself? like maybe selecting the reflective object and “create cubemap”?

it seems its a bit too complicated, especially when u see the water reflective material just works with one click.

I believe there was a good description of the process in one of the Unite 2008 videos.

If you have Unity Pro, you could also use the above shader on the wiki for your reflective floor. It works quite well!

There’s the video I was referring to. I discusses using the camera->rendertocubemap wizard to automate generating cubemaps for your reflections.

thanks, that was very useful…

now i feel stupid cos i cant find that wizard… ive created a cubemap, ive selected my floor, but now theres no rendertocubemap wizard anywhere

im using unity 2.5 pro on a mac

am i missing a plugin or something?

As was mentioned in the video the source for his editor wizard, along with an example of using the method real-time, is included in the documentation for Camera.RenderToCubemap().

That can be found at the link below.
