the reason i want that is: my coordinate system is different from JPCT system, so an object loaded from 3DS has wrong orientation and wrong lighting.
a way to solve this is i switch vectors of the vertices.
or i have to find other ways.
ps: my coord system is forward-left-up.

i want to change some vertices in an object loaded from 3DS or OBJ file, and create another object from these vertex data.
can i do that?

can the game be downloaded somewhere else except from google server? i can't download the game.
although i am not an RPG gamer, i would love to see a complete game made with JPCT engine and by the author of JPCT engine

i found out i must call both setFOV and setYFOV to have the correct size of shadow.

i found that the horizontal size of the shadow is correct, but the vertical size is smaller. the wall is smaller in vertical dimension, so it seems the receiver should be square or the shadow would be deformed. is that so?

here is a screenshot

i used Shadowhelper to cast an object onto a wall, and noticed that when light is far away, the shadow was smaller than the object. is it normal? shouldn't the shadow be at least as large as the caster?

the opaque objects (such as the green part) are covered by fog correctly, the beach is not.
i'll look into the shaders.

yes, it's the beach that appears dark. but the beach is also from the png image, just the color is yellowish instead of white.
the beach and the white color part are both opaque part of the png image.

please look at the shore line of the island. it`s from a png image with 1bit transparency.
in the 2nd screenshot the shore line looks dark on the far side.

i have a transparent object with the same fog setting as other opaque objects, but when fog is dense ( close to farclip), the output color is not close to fog color. so the transparent object stands out when viewed far away.
is there a problem with the blending method?

here's another question: in a World, are transparent objects rendered after (speaking of time) all opaque objects?

it's not very necessary. i just wanted to know.
sometimes, it can be used to save memory, such as different LODs of an object use the same VBO.

i read the doc about shareCompiledData. it says the objects must have the same Mesh instance, then how can i define different primitives for the objects?

now i have another question, how can i use multiple shaders on an Object3D. i think i have read somewhere that an object can have several vertex shaders and fragment shaders in a row.
the reason i want this is that i don't like to modify the default shaders.
