Help!

Hi, I'm pretty new to max so that’s why I have so many questions. Please be patient.

Trying to do an interior shot of a basic hospital room. Applied the blue material to the floor and the colour has bleed all over the walls. Is there a setting somewhere where I can control this?

 

Also I am using sunlight through a window and have set it to Raytrace shadows. The thing is I would like softer looking shadows that don't have such defined edges. Is there a setting that will allow me to achieve this?

 

The floor is lino (horrible I know), I am struggling to get decent settings for it, it should be kind of reflective but the reflections should be very blurry, the ceiling tile is similar it is a kind of flat metal. Is there a way to achieve this.

 

Any other general advice would be greatly appreciated!

I managed to find the colour bleeding control. You have to make the material an architectural material and the setting is in there!

But if anyone has any idea's on making the floor ceiling and how to soften the edges of the areras directly lit by sun a little better that would be great!

Hi,

 

If the only light is coming through the windows and hitting the floor, then you will get those kinds of results with the radiosity engine. Wait until the scene is set, then play with radiosity.

 

For softer shadows, typically you would create Area lights rather than point lights like the standard Omni or Spots. The photometric Area lights will take a lot longer to render, though.

 

For your floor reflections, use a Flat Mirror map in the reflection channel. In it's parameters is a Blur setting that you can adjust.

 

Have fun!

Thanks a lot for your help. I'll give them a try!

Just a little trick I've used before for floor reflections in animations...

 

While working on an animation project with 10 condo interiors I had to find every way possible to get my render times down. My scenes were lit with fakeiosity, but adding the flat mirror map to my tile material would still add a bit to the rendering. I simply placed a plane just slightly above the floor, applied the flat mirror to it and adjusted its opacity and reflection values. This also helped me tone down some of the hotspots I was getting on the floor from all of the lights. This might be something everyone here's already done, but I thought it could be of use.

In addition to the other posts, make sure you adjust your refine interations to about 25 or so. And your refine interations are high.
