Strange problem with "Edge Mode"
« on: May 26, 2015, 06:09:53 PM »
We have another problem today, possibly associated with "Edge Mode".

The attached images show a grass edging which uses edge mode to keep the edges nice and neat, but the bits of grass that have been cut off seem to be affecting the Alpha channel and not allowing the object behind to show.

Any ideas?

These artefacts could be caused by exceeding V-Ray's transparency limit (as mentioned in this related post). There are two possible solutions to avoid these issues:

a) Use lower density values, increasing Distribution Map -> Density X/Y Size.
b) Under V-Ray render settings, increase Global switches -> Max transp. levels (default value is 50). Sometimes it may be necessary to modify Secondary rays bias also.

Hope that helps.

Best regards,
