bug, radiant, vertex, drag tool

(aaa3) #1

HELLO, i have encountered an annoying bug (or not a bug?) in 1.5. before trying do do that few ones in 1.4 (dont wanna dl and install), im asking if anyone have any idea on it.

i was making some nice purely handmade terrain, and i didnt have that problem in 99% of the brushes, and those which it appeared on were no way different from the others, nothing special were with them.

i was selecting a certain vertex, trying to move it in 2d, and rad automatically switches to an other one, left form the originally selected. i tried to quit and restart rad but no effect. tried on other bushes - everything was perfect. tried again on those - nothing change, still bugged.

and another, slightly related question - is there a way to manually lock certain vertices from changing? ill post a screen, coz it was quite systematic how it did change.


selecting “2”, changing to “1”. on the neighbouring brush, selecting and moving 3 was fine but selecting “4” was producing the same effect, rad changed to the un-numbered vertex of that brush (above 2).

having the bug only in that area, with only some 2-6 brushes.

perhaps this is the problem:
if the vertex points are like this:
|x| x can be moved -> another point: |a|

|y|   y can only moved to the right inside the brush but not outside it!   |b|

|z|   z can be moved                                  |c|

This happened to one of my brushes if they were changed via dragging edges vertexes Or clipping.
I dunno what caused this problem.
try to move another point away from the brushes center, then move the point you couldnt move and then move the first point back where it had been before.

Delete the brush and remake it.

half solved, thx 2 everybody 4 the replies; isbowthen i couldnt understand :P; death not working; the “solution” (better to say workaround) was to change view in 2d window with ctrl tab.
i still say its a bug coz i was editing all the other brushes of the riverbed in the same way, form same viewpoint, many of them had very similar layout, and still only ther appeared the error.

I cant even drag vertexes in 1.5.0 oO
when I select 1 side it just drags the whole side anyway even tho just 1 corner is selected, drives me crazy

@aaa3 yes my english is too bad!
and i was only half right.
@stealth
if you already tried “grid 2” or something other small grids then you mutated the brush too strong.
did you try to do it with a simple brush?

(stealth6) #7

I do it with a triangle brush like on aaa3’s screnshot and I use all grid sizes so probably even smaller than grid 2

(isbowhten) #8

do it with a simple rectangle brush and clip it to triangles ^^
or download radiant 1.4.8 it works ^^

ur problem may be something else. 1st, you too try it from another view. but 2nd, what i really wanted to say, 1.5 dont let u transform the vertices in such a way to make the brush concave, instead moves some (2?) other vertices to keep the brush convex. but u should play with it, trying to move the vertices different directions, sooner or latter u will learn :wink:
maybe start with a square, cut it half to make it a triangle based …er… stuff… (sry my english also :P)…, and then select one of the upper vertices, and try to move it first upwards (direction “z” in rad). and choose such a 2d view, that in there is no other vertex nor behind it nor the closer side to u of it, only that one. it should work. and basic maths: 3 vertex is always in 1 plane but 4 arent!! thats why, if u dont triangulate the brushes and try to deform simple square (all faces are 4 sided) ones, u will get very poor result.

wait im uploading a real picture

EDIT - 2008. IV. 21. - Found another workaround! try to gently carefully move the buggy vertex in 3D only 1 unit. Then check if it was moving only in the desired axis! (And check twice!) Now you are able to move it in 2D, yay ^^
