[SOLVED] Texture Gridding

[tmorris]

After converting to 2.2 we are getting some interesting behavior with textures in motion. Things look really good when standing still but often times in motion you will see a subtle gridding pattern applied to the texture. For the most of our vegetation I am able to find a new balance of transparancy/alpha settings that will remove the artifact but not without losing some of the quality we had before migrating to 2.2.

 

However in some cases it is either very difficult to find a good combinations of settings that maintains the visual goal or the material itself does not directly support parameter modifications that will remove the artifact. I have attached a screenshot that shows the artifact on a river material.

 

Is there an easier way to get rid of this artifact then re balancing all of our material transparencies? am I missing something?

 

Thank you,

Terrence

Hi Taylor,

 

Could you please check if this issue can be reproduced with disabled TAA (render_antialiasing 0) and Motion blur (render_motion_blur 0)?

Thanks!

Hi Silent,

 

When I turn those both of those off the effect gets more noticeable.

Hi Taylor,

Thanks for the screenshots. Now it is clearly visible that it is Translucent option enabled in material settings. Enabling TAA will help to minimize this effect.

We will improve translucent option in the future SDK updates (probably, in 2.3) so this noise will become less visible.

 

Sorry for the inconvenience caused.

Hi Silent,

 

Thanks for the response, it is good to know what is going on.

 

Unfortunately with our current release plan we dont have the time to upgrade to 2.3 and the effect is not suitable for release.

 

Do you have any other strategies we might use to help make the noise less visible?

 

Thanks

Hi Taylor,

 

You can fully disable translucent noise by editing data\core\shaders\common\light\world.h and removing following code (from line 123 to line 127):

#ifdef QUALITY_HIGH
   softness += translucent * nrandTAA(IN_POSITION.xy,4.0f) * 0.1f;
#elif QUALITY_MEDIUM
   softness += translucent * 0.02f;
#endif

Thanks!

Thank you, we were able to fix this by forcing the translucent noise to medium quality
