Fuzzy texture problem

[Fred Wasson]

Hi guys,

I’m very new to the 3d game and I’m looking for some advice. I’m trying to do some basic renderings for a builder and would appreciate if some one could help me with a question. My siding and roof textures are rendering fuzzy or blurry on the surfaces that are at a grater angle to the camera. Any help would be much appreciated.

Thanks

I've had the same problems with large textures in max when rendered at an angle. Try reducing the size of the texture file (~600x600).

 

I'm sure there's a better answer than this though.

Are you using a bump map? Bump maps at angles dont work too well.

2 solutions:

1: Use displacement

2: Model the siding.

 

I would go with 2. For that building it should take around 20 minutes. Roof tiles may take a little longer to make, but will be well worth the effort.

[Fred Wasson]

Ok, maybe someone can explain this. When I apply it to a box at the same angle it looks fine. See attachment.

Then it may be your smoothing groups:

 

1: Select the wall object

2: go to sub-object (3) and select all polygons (ctl-a)

3: scroll down the modify panel to 'smoothing groups'

4: click 'clear all'

5: cross fingers

6: hit render

 

Edit: it may be in reverse, ie, the box has better smoothing. Do the above for both the box and the walls/roof. If the texture disintigrates on the box then the sg need to be applied to the wall, not removed.

No, Not it. Thanks for the quick replys.

Ill keep trying

[Tommy L]

Well as a quick fix you can just move that box over the offending return wall! Honestly, Id model the siding and defo model the roof. It will make a huge difference. And if these are stills, photoshop the grass

Adjust the blur value in the maps that seem to have trouble.

 

I typically use 0.2, but there are some who completely turn the blur off by disabling map filtering.

Looks to me like your applying that UVW map in a planar fashion to the front of your structure. Try UVW mapping it in a box fashion.

WOW!! Thanks Beeste. you were right. I changed the blur to .1

[DanGrover]

As Beeste said, it's that blur value - but beware! The reason it is set at 1.0 by default is because otherwise you will almost definitely get terrrible moire or other flickering patterns if rendered as an animation, as 600px of textures gets hammered down to about 20px in the render as the angle becomes more and more accute!

i used to have a script that would reset blur values on all textures to any value you specified, i'll try and dig it out. reset all mine to .1 in a zombie like fashion without thinking now.

[Nic H]

yeah textures must be at 0.1.

keeping it at 1.0 is a good way to make things look shit, especially floors

[braddewald]

Matt, what script is this that you are using? Can I get it somewhere?

[mattclinch]

maps = getClassInstances bitmaptexture 

[color=#b1b100]for[/color] m in maps [color=#b1b100]do[/color] [color=#66cc66]([/color]
   m.coords.blur = [color=#cc66cc]1.00[/color] [color=#3cb878][i]--set this value to whatever you want[/i][/color]
[color=#66cc66])[/color]

credit to the original author.. but can't remember where i got this from.
