Dear developers of language, the command

SET OBJECT SPECULAR Object Number, Color Value - does not work

Not for one types of objects, we tried on plein object because we work. We make object, we impose a texture, starts to highlight and occurs nothing. In version 5,9 and 6,0 works normally, and in version 6.2 is not present, for this moment ambient light was 100. I very much ask you look this mistake, because we have very much got stuck it on it.

Or in the command that that has changed?

If that send me the letter on dantemcmanus@mail.ru

Help.

You've raised this before and, so far, no-one has given you a simple straightforward answer. I tried the following, which I expected would give a red specular reflection depending on the camera's position. Everything I've tried fails so perhaps someone who knows what I've done wrong could tell us both:



Edit: I've just tested my bumpmapper posted yesterday on the main DBP list using a flat normal map and the specular reflection shows up fine. So it ain't the object or lack of bumpiness that's at fault - which is what Richard Davey suggested when this problem was raised earlier.

Thanks. That is exactly the sort of simple answer that is needed!

Next two questions:

1. Why doesn't it tell you this in the "Help" file?

2. Why doesn't it work for light 0 (which is already present)?

[And, of course, a third question: How did you find out? Guesswork?]

I can't answer that question.

It will if you want to change light zero to a point light.

Can't remember.Probably.

I believe it was during the release candidates that the lighting system changed.Something about DirectX.Questions were posed then and not answered sufficiently.Wheather or not this is a bug i do not know but i do know that specular does not work with directional lights.

Thanks for the further explanation. Hopefully the new Help files will explain all this. There doesn't seem to be any good reason why directional lights don't give a specular relection - sounds like a bug to me.

P.S. Talking of new help files, where are they?

I wasn't trying to say you're new, it means something else.

(perhaps my sarcasm is regional)

Good question... where are the new help files. We were promised they would be here months ago.

They keep promising, but they're never gonna deliver. I gave up a while ago - now, whenever I find a thread like this, with something that should be in the help, I add it to a text file on my hd, for reference purposes.

Maybe someone in the community should just make a new set of help files themselves.

Which reminds me - I haven't yet replied to your questions about FX files. You haven't been forgotten ...

That is very good advice.

I just figured out that LOW SPECULAR POWER has a larger specular effect than higher specular power. You want lots of specular do the following:


set object specular power cur_obj,0

If I use any power greater than 1 I see no specular effect at all !

It does seem bizarre that there is no specular for directional lights. I fudged a solution. It seems that the lighting from a point light does drop with distance, but, near to the light, it is constant.

Therefore, to simulate a directional light, i put a point light a LONG way away (in the direction required), and make the light range significantly bigger than this. About 10x seems to work.

So, assuming you had a world, or scene that was, say 100 units across, centred at the origin, instead of using



instead use
