Problem with 3D plants/opacity Maps

[JustinTuaylou]

Hello Everyone:

 

I actually have two questions about using 3D plants.

 

1. I have this red maple tree in my scene, but when it is rendered at actual viewing distance (20 feet or so) these white outlines appear around each leaf. When the tree is rendered at a close up, the outlines diminish. I have attached two images two show what is happening, I have adjusted the opacity maps of the leaf material (.jpg diffuse with separate .jpg opacity map) but to no avail. I have noticed this happening before, but never so drastic. Does anyone know what is happening?

 

 

2. I have bought 3D tree models from XFROG and Turbosquid because their standalone renderings look accurate and realistic, but as soon as I place them into a working scene I am HIGHLY disapointed with the way they look (and the money they cost). Can anyone recommend a company who sells high-quality, realistic, and accurate plant models?

 

Thanks,

 

Justin

Is your opacity map in the refraction slot or Cut out? Cut out is better. To get rid of the white outline either set the maps filtering to non or dial the blur to 0.001 (or as low as it will go)

 

As for the other, they a problably looking bad because you havn't set the materials and lighting right. Bear in mind that most of the images used to sell these libraries have been touched up after a heck of alot of time been spent in Max to get them right there. Foliage is very tricky to get right so be patient and keep tweaking.

I've recently purchased the Xfog Oceania 3 library and after using them in a few projects I have to say that the quality is pretty good. I've had no issues in geting fantastic results out of the Xfrog products. I have made a few adjustments to the materials but that's it. The way I see it though any purchased pre-built stock item still needs some extra work to achieve realistic results. I'm yet to find anything that is even close to a simple drag and drop into a scene, hit render and expect realistic photo quality.

 

On top of that, like Justin Hunt has already mentioned; if your materials, lighting and render settings are not correct they will make even the most highly detailed and accurate model look very average and of poor quality at render time.

That removed the outlines, thanks for the feedback everyone.
