I already said it doesn't fix it in another thread.
sixus1, I appreciate that you wrote all that to help people, but I must respectfully disagree. Bump maps and normal maps encode the same information, but in a different way. The normal map is faster/easier for a real-time renderer to decode, but the results are the same as with an equivalent bump map. Bump maps do react to light. In a software-only renderer like Poser which is spending tons more time on other things, the normal maps have no particular speed advantage. Furthermore, a bump map intensity/depth can be dialed at will, whereas a normal map will always produce the same intensity/depth - it's baked in. That's why it's faster - the effective change in the normal is hard-coded in a normal map. The effective change in the normal must be calculated in a bump map. The fact that it is calculated offers the opportunity to modify/alter the results of that calculation by adjusting the bump depth.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
