here is a render I am currently working on. In the wireframe version you can see that there are a bunch of flowers around the sundial, however when I render it only a few of the flowers show in the render. I don't believe the flowers are behind the background. I have looked at it with a number of camera angles and they seem to be in front of the background, but I can't figure out what else would case them to disappear on render :(

Any suggestions would be greatly appreciated.

hmmm...dont know how to solve your problem but you did solve mine!! that bent ground plane sure solves my composition problem with shadows!! :::::goes to model a ground plane::: =)

I can see them- they are not to bright and washed out in the background- have you rendered it bigger at like 1024 and looked? You can adjust the base color on the blue to make it a touch brighter.

I've sometimes had props not show up in a render. Can not explain why, but I solved it by just exporting them as an OBJ then re-importing.

I ended up deleting the "missing" ones and adding them again and then placing them using a different camera angle vs the main one and they decided to grace me with their presence.

I have dealt with this prob before. Usually it is a memory thing caused by an abundance of textures on other props and figures. 1. Save your work and Quit Poser before rendering. That will delete unused textures from the memory. Re-open your image and try rendering again. 2. Or, as stated above, delete the props and re-import them. Try rendering again.
